Sometimes, Shoto can be a little socially inept.
He knows this. He knows it stems from his isolated upbringing, his complicated family dynamic—though he hates how often he has to attribute parts of himself to that. But being at UA helped, being surrounded by more ‘normal’ people (if you could say that?) was helping. He’s learning, slowly but surely, and he finds himself enjoying all these new experiences, even if he’s a little late to them.
Enter you.
You’ve only been dating him for a few weeks, barely enough time for him to grasp the basics of being someone’s boyfriend. But he wants to get it right, especially with Valentine’s Day just three days away.
He never thought much of it before. It was just another date on the calendar, something he associated more with pink-themed store displays than anything meaningful. But now, it feels important. A chance to prove himself to you, to show that this relationship is worth your time. That he doesn’t need you to guide him through everything.
Now it’s a day where he’s supposed to do something special for you.
For the first time in a long time, Shoto Todoroki feels out of his depth.
He has no idea where to start.
Unfortunately, none of his friends seem like they’d have good advice. The only one who crossed his mind for a second was Denki, but that idea was immediately discarded. He could already imagine the kind of advice he’d get, some overly complicated plan involving sunglasses and, for some reason, an unnecessary explosion.
Which brings him to now, Tuesday morning, staring at Natsuo’s contact.
He’s pretty sure Natsuo has a girlfriend, or at least some experience in romantic endeavors. In their limited interactions, Shoto has picked up on a few subtle signs. There were the late-night phone calls he’d catch Natsuo having in the garden, the way his older brother’s face would turn bright red when he thought no one was watching. Then there was the time he overheard Natsuo asking Fujumi for advice on gifts around Christmas—specifically romantic gifts. And, of course, there was that one unfortunate day when Shoto happened to notice a collection of what he could only describe as… love marks on Natsuo’s neck, which left him quietly questioning his brother's life choices for the rest of the week.
So, with all this information he has gathered, Shoto decides Natsuo is the best course of action. He did briefly consider asking Fujumi for advice, but something told him she’d get far too excited and blow everything out of proportion. She’d probably give him a long lecture too. He doesn’t want that. He just needs a little guidance.
The phone rings once, and then twice, and then he’s sent to voicemail. Shoto pouts down at the screen. Before he can go to google as his second choice for help, a text comes through first.
[9:03 AM] Natsuo: Sorry, man, I’m in class right now. What’s up?
This feels strange, asking for relationship advice. He’s not used to talking about this kind of thing, especially with his brother. After a few seconds, he types:
[9:04 AM] Shoto: I need help with Valentines day.
The reply comes quickly:
[9:06 AM] Natsuo: Valentine’s Day?
[9:08 AM] Natsuo: Wait... are you dating someone? Since when??
Oh, he forgot that he hadn’t told his family yet. He wasn’t planning on telling anyone until things felt a little more serious. But I guess asking these sort of questions made it somewhat inevitable.
[9:10 AM] Shoto: Yeah. I have a girlfriend. We have only been dating for 3 weeks.
[9:11 AM] Shoto: Please don’t tell anyone yet.
[9:13 AM] Natsuo: Alright, alright, I won’t say anything. I get it.
For some reason, in this moment, Shoto feels his heart warm a little. He’s never really had the true brotherly relationship. But this feels normal for them, domestic.
[9:15 AM] Shoto: Thanks.
[9:17 AM] Natsuo: Haha! So serious! Dont sweat it lil bro!
Nevermind, Shoto scowls, he hates his big brother.
[9:19 AM] Shoto: Can you give me advice now.
[9:21 AM] Natsuo: Ah, right, the actual reason you texted me.
[9:21 AM] Natsuo: Hmm. Try not to overdo it, since it’s still early.
[9:21 AM] Natsuo: Maybe try something lowkey but personal?
[9:22 AM] Natsuo: Don’t overthink it, dude. I’m sure at this early stage the fact you are even trying to do anything will be appreciated!
[9:23 AM] Shoto: Can you give me an example? Just so I’m sure I’m on the same page.
[9:25 AM] Natsuo: Hm… okay. Like a handwritten card? Or a picture of you both? Sum like that.
Shoto’s mind goes blank for a second.
[9:26 AM] Shoto: That seems too simple.
[9:26 AM] Shoto: Have you ever been in a relationship?
[9:28 AM] Natsuo: Going to pretend that wasn’t rude! 😒
Shoto’s brow furrows.
[9:28 AM] Natsuo: But yeah, I’ve been in a few. Trust me, the simple stuff always hits.
[9:30 AM] Shoto: I’ll try it. Thanks.
[9:31 AM] Natsuo: Anytime bro! One more think tho.
[9:32 AM] Natsuo: Since you're dating now... uh, just don’t forget to be... responsible, okay?
Shoto frowns at the screen. [9:37 AM] Shoto: Responsible?
[9:39 AM] Natsuo: You know what i mean! Haha
[9:41 AM] Shoto: No I do not.
Natsuo’s reply comes quickly, almost too quickly.
[9:43 AM] Natsuo: Look, I’m just saying. Protection and all that. Haha
Shoto’s eyes widen, the full realization dawning on him. His face flushes red instantly.
[9:43 AM] Shoto: I do not need this advice. Thank you.
Natsuo doesn’t stop there.
[9:45 AM] Natsuo: Hey, I’m just trying to help. You’re my little brother!!!
Shoto stares at the screen, blinking rapidly, his face still flushed.
[9:47 AM] Shoto: I appreciate it. But I’m fine.
[9:47 AM] Shoto: Maybe speak to your sexual endeavours about this.
[9:50 AM] Natsuo: what???!??
[9:47 AM] Shoto: To stop biting you.
[9:52 AM] Natsuo: You know what, I’m just gonna pretend you didn’t say that.
Shoto quickly types, trying to change the subject before it gets any worse.
[9:54 AM] Shoto: Anyway, thanks for the other advice. I’ll try what you suggested.
So, something personal huh?
~
Which brings Shoto to Thursday afternoon, the day before Valentine’s Day.
So far, he thinks he’s managed to keep his plans for you under wraps. Maybe a little too well—because just yesterday, during one of your usual study dates, you had paused mid-note-taking, tapped your pen against your lip, and tilted your head at him.
"You’ve been too quiet lately."
He had blinked at you, unsure how to respond. I’m always quiet wouldn’t exactly work when you already knew him well enough to see through him.
It was... cute, in a way. How easily you picked up on his shifts in mood, even when he thought he was being subtle. He didn’t really know what to do with that kind of attention. But he liked it.
He just hoped you didn’t suspect anything yet.
Anyway, today for mission valentine, he is in the mall.
He ended up taking Natsuos advice somewhat, taking the time to write a detailed and heartfelt card with his feelings to you, but something was still missing. He knew to get flowers, ordering a custom bunch on Tuesday night to be delivered in time (Thank you Endeavour name drop), but despite Natsuos advice to keep it ‘lowkey’ he was on the lookout for a little more.
He’d been wandering around the mall for the last twenty minutes now, his frown growing more pronounced with time. How do I put this feeling into words? How do I show her how important she is to me? How long I’ve waited for this…
He stops in front of a tourist stand. Surely, a trip is too much…
“Shoto???”
His head snaps up at the familiar voice, crinkling the leaflet in his hand as he turns. But the flash of green quickly eases his heart.
Midoriya.
Shoto exhales, releasing tension as his friend approaches, eyes bright with curiosity.
“I thought that was you!” Midoriya says, stopping beside him. His gaze drops to the crumpled leaflet in Shoto’s hand, curiosity flickering across his face. “Uh… are you planning a trip?”
Shoto follows Midoriya’s gaze down to the brochure in his grip—some kind of couples' getaway package, complete with scenic resorts and heart-shaped chocolates. His expression remains neutral, but internally, he’s horrified.
“No.” He drops it back onto the stand like it burned him.
Midoriya blinks before smiling. “Oh! Are you here for Valentine’s Day shopping?”
Shoto doesn’t answer immediately, which is answer enough.
Midoriya’s eyes widen. “Wait… you are?! Does that mean—do you have a girlfriend?”
Shoto feels a strange mix of emotions—mild regret for being spotted, slight panic at the idea of the entire class finding out before he’s ready, and, underneath it all, a small, hesitant sense of pride. Because yes. Yes, he does.
“…Yes,” he admits at last.
Midoriya gasps, practically vibrating in place. “Shoto! That’s amazing! Who is it? How did I not realize?! I mean, I thought you were smiling at your phone more, but—”
Shoto feels his face heat up as Midoriya rattles off every small detail he had apparently noticed. The way he texted more. The way he seemed lighter. The way he—
“—just kind of smile at nothing sometimes?” Midoriya gestures vaguely.
Shoto presses his lips together. Was it really that obvious?
Midoriya suddenly gasps again, eyes practically glowing. “Wait, does that mean this is your first Valentine’s Day with her?! That’s so special, Shoto!”
Shoto exhales, rubbing the back of his neck. “Yes. That’s why I’m here.”
Midoriya’s enthusiasm doesn’t waver. “Okay, okay, no pressure! But what’s your plan? Do you need help picking something?”
Shoto hesitates. He doesn’t mind Midoriya knowing—he’s probably the safest person to tell, outside of Natsuo. But still, something about sharing this part of his life makes his throat feel tight.
“…I have a card,” he says slowly. “And flowers. But I wanted something more personal.”
Midoriya hums in thought. “Something personal… Oh! What about an experience? Like a day out or something—maybe not a whole trip though...”
Shoto pauses. His mind flickers back to a few weeks ago—how your eyes had lit up when you talked about that one artist. The way you always played their music during study dates, humming absentmindedly, completely lost in the moment. He remembers the song playing in the background as you gently traced your fingers along his face, both of you hesitating, then leaning in for a soft, tentative first kiss. The way you had giggled afterward, your smile so warm it made his chest ache.
“…I know what to get,” he says, turning on his heel.
Midoriya blinks. “Oh! Okay! Do you want me to come with—”
“No.”
Midoriya chuckles. “Alright, alright! Good luck, Shoto! And, um, if you ever wanna talk about—” He gestures vaguely, expression warm. “You know. Relationships. I’m happy to listen.”
Shoto gives him a nod—one that, after a moment, carries a little more meaning than just goodbye.
~
Friday morning, Valentine's day. He had woken up to a good morning text from you, and motivation messages from both Natsuo and Midorya. And suddenly he was nervous in a whole different way.
It wasn’t like him to be uncertain. But there was something about today, about this. Every time you looked his way, his chest tightened. His fingers would flex in his lap, as if he could do something with that energy.
The problem was, he couldn’t seem to get a moment alone with you. The entire class was buzzing, and as the day went on, his nerves grew. How was he supposed to give you the gift without feeling awkward? He hadn’t really thought about how it would feel to give a present to someone he cared about. What if it wasn’t enough? What if it wasn’t right?
But then, at lunch, the bell rang, and that was it. The moment he’d been waiting for. The class broke apart, but his eyes found you instantly.
He took a breath, gathered his thoughts, and stood. You hadn’t noticed yet, so he took the opportunity to walk over to where you were standing.
“Hey,” he said quietly, and when you turned to him, there was that familiar warmth in your gaze that made his heart beat a little faster.
“Hey,” you replied, the smile tugging at your lips.
“I…” He hesitated, feeling a sudden tightness in his chest. It felt strange to be so out of his element. “I have something for you.”
“Really?”, your eyes widened for just a moment, the surprise softening into something warmer.
He looked at the ground for a second, clearing his throat. “I... I wanted to give it to you, but... maybe... somewhere quieter?”
You tilted your head, sensing his nervousness, and nodded with a soft smile. "Of course, Shoto."
A few moments later, Shoto and you were perched under a bright tree, the sun out as he watched his classmates flutter around. You were looking at him expectantly, but not with judgement, a slight blush across your face. Now or never, huh?
His hand shook ever so slightly as he reached into his bag and handed you the envelope. He avoided your gaze, feeling the heat rise in his face despite himself.
You carefully opened it, scanning the card. He could feel your attention on him, the way you were taking in the words he had carefully written. His throat felt tight, but he waited, watching the way your expression softened.
“This is… really thoughtful, Shoto,” you said, your voice gentle.
He didn’t know what to say to that. It was strange to hear someone speak to him like that—like he had actually done something right. “I wasn’t sure if…” He stopped, unsure of how to finish. “I wanted to make sure it was right.”
You smiled at him again, this time the warmth more tangible. “It’s perfect,” you said, and there was something in the way you said it that made his heart calm, just a little.
Without thinking too much about it, Shoto pulled out the second part of the gift—the tickets. “There’s… one more thing.”
You looked at the tickets, then back at him, confusion flickering across your face for a split second before it was replaced by recognition.
“These are for the concert?” you asked, shock creeping onto your face.
Shoto nodded, his expression as neutral as he could make it, though he could feel the tension in his shoulders. “I remembered you mentioned wanting to go,” he said. “I thought… if you still wanted to, we could go together.”
You blinked, clearly surprised. For a moment, Shoto was afraid you might not like it—but then your smile grew wider, and it felt like the weight had finally lifted from his chest.
“Shoto, this … this is too much! You didn’t need to do all of this for me..”
“I did,” he said simply, looking at the tickets. “I wanted you to be able to go.” And, selfishly he thought, he wanted more alone time with you. As much as he could manage.
You stepped closer, your hand lightly brushing against his. “Thank you,”
He nodded, a faint flush creeping up his neck, it had all been worth it. “I’m glad you like it.”
“I love it, Sho…” You looked away for a moment, cheeks flushing slightly, before murmuring, “But this totally overshadows mine…”
Shoto blinked, “What...?” he asked, a little surprised.
“I didn’t know we were doing big gifts, okay?” you raised your hands up, like trying to defend yourself. “So I just made you something, it’s just little and—”
His heart softened, for some reason he didn’t even consider you would also get him a gift. He stepped a little closer, catching your gaze. “I’m sure whatever you made is perfect.” His voice was gentle, reassuring.
You hesitated for a moment before reaching into your bag and pulling out a small, neatly wrapped box. "I… hope you like it," you said, a little uncertain.
"I’m sure I will." He took the box from you carefully, his fingers brushing yours for a second as he did, looking up from the box to your gaze, making sure to keep this memory burned into his mind.
He gently opened the box, not wanting to disturb your work, before moving the tissue paper out of the way. He paused.
It was a scrapbook.
It was small, about the size of a small notebook, with the first picture of you both plastered on the front page, surrounded by little stickers. His hands trembled slightly as he held it, the weight of it making his chest feel heavier than usual.
His thumb traced over the cover, heart thudding in his chest.
“It’s not finished yet!” you sputtered, nerves bubbling up. “I’ve only filled in the first few pages, but I was thinking we could fill it in together and—” As you spoke, his fingers flicked through the first pages. There it was—your first date, the receipt from the boba store, the cinema tickets. As he flipped through, a soft, warm feeling began to bloom in his chest. It was clear now what Natsuo meant. Personal gifts, something with real meaning, were truly unbeatable.
Shoto could barely speak, eyes tracing over each little detail you’d added.
“I…” He swallowed, a lump forming in his throat as he searched for the right words. “This... this means a lot.”
He met your gaze, his chest tightening with something more than gratitude. Everything he had felt in the last few (amazing, complicated) weeks surged to the surface. You’re mine. He had someone who took the time to do this for him, someone who cared enough to leave pages in a scrapbook just for him to fill.
Thank you doesn’t mean enough, so he lets his body talk for itself. Even though everything was still new—still uncertain, still so fragile—he couldn’t deny how much he wanted to be close to you. It’s only been a few weeks, and nothing has been exchanged except a brief kiss or two and some light hand holding. But despite the lack of his experience burning in the back of his mind, he can’t help but lean in.
He reached out, hand gently brushing through your hair, pulling you closer. Even as the thought nagged at the back of his mind—we're in public, no one knows yet—he couldn't bring himself to care. The happiness swelling in his chest was overpowering.
His lips meet yours, and you must feel it too, in the way this kiss is more powerful than the rest. It was still new, still uncertain in some ways, but there was an undeniable tenderness that made Shoto feel like everything had led to this moment.
He could do this forever. He wanted to. And maybe—just maybe—he’d get to.

i've been writing so much angst lately this was kinda hard. But enjoy loves! and happy day of love! ε(´。•᎑•`)っ 💕
I'm so sorry but ever since that teen Hawks page was translated on twitter I can't stop thinking about it. like. Mera treated him like a person. he was assigned to Hawks when he was already a teenager. did no one treat him like a person before then? was it such an uncommon occurrence that it seemed special when someone did? I mean, they didn't even let him have a person's name. they gave him a hero name, and to the HPSC, that was the name of a tool. of a product. they basically bought a child and treated him so coldly that Mera stood out to him because he treated him like a person. the bars of my enclosure.
Going to a cafe just to sit down and read a book, and when you go for a quick trip to the restroom, you come back to your favorite tea and pastry on the table—along with a piece of paper folded up underneath one of the plates.
When you open it, you’re stunned to see a penciled sketch of you, sitting in the cafe reading, along with a caption, written in that familiar, perfect script you’ve come to memorize by now:
I yearn for a fraction of the attention you’re giving your novel. I hope this captures it, even for a moment, however fleeting.
Sincerely yours.
[OC] Gently holding berry

thinking about how katsuki is obsessed with you when he's drunk! it doesn't happen very often due to how health conscious that man is, but when he is drunk, he can't keep his eyes—or hands, off of you. and it's not even sexual, the way he gently rests his hand on your lower back, or how he drapes his long limbs and loose body around you. he presses little kisses to your head every so often and drags you to sit on his lap in the middle of conversations, his focus always on you.
if you get up to get another drink, he's close behind, hands gently resting on your hips as you lean against the bar to talk to the bartender. and if you’re giggling at little too much over what the bartender is saying, katsuki gets a little pouty and will gently tug on a lock of your hair, letting you know that he’s still right behind you.

SUMMARY: When your pro hero boyfriend comes home to find you studying, he suddenly takes a great interest in helping out. You find his methods... questionable. TAGS/WARNINGS: nsft, hysterical literature (reading out loud while sexually stimulated), pro hero deku, deku still has ofa, support tech grad student reader, slight intelligence kink, gn + afab reader, cunnilingus, established relationship, aged up characters, fluff (3k) NOTES: Hi guys! I have been in survival mode as of late and the writing has been slow going; my sincerest apologies for how long it’s taking me to burn down my @ficsforgaza backlog. But I finally had the time & energy on my hands this weekend to work on this one and I had such a blast!! I hope I’m not too rusty–and if I am, I hope you enjoy it as much as I loved writing it regardless lol. Love you and thank you always for your patience. Happy Holidays!!
Sometimes, you thought you could tell your boyfriend was near, even before you heard his key in the lock.
It was something to do with his power, you’d always suspected—as a support engineer unduly interested in other people’s capabilities, you’d spent hundreds of hours turning it over in your head. It was the unnatural immensity of other people’s powers, you thought, pulling and coiling just beneath the surface of Izuku’s skin. In close proximity, after prolonged use, its presence felt like a shiver up the back of your neck.
You felt the barest hint of it now, an unsettled feeling creeping into the marrow of your bones, and you sat up on the couch just as you heard the scratch of Izuku’s keys at the door.
One For All fit cleanly into Izuku’s own unwavering intensity somehow, like the last piece of his puzzle. Though one would certainly never think so looking at him as he spilled through the door, pink-cheeked from the cold, all bright eyes, sweetly angelic features, and a riot of wild green curls. He looked windswept from the biting winter breeze. He also looked too kind to be carrying the sort of power he did—too sweet and eager and lovely.
“Look what the wind blew in,” you grinned at him over the back of the couch, after assessing he was well. Your eyes tracked the sinuous movement of those broad shoulders as he yanked his mouthguard over his head, the flex and pull of his bicep as he hung it beside the door. He was moving without pause, no sign of injury or muscle strain , and his suit was intact. Ordinarily you didn’t mind if there was a bit of shredding about the abs as long as he came back to you whole and hale, but in the winter you didn’t like him wandering about risking the chance of frostbite.
Your heart fluttered when Izuku returned your smile with one of his own, so beautiful and bright, chasing away the cold he’d tracked in like a warm sliver of sun.
“Lots of small, easy fights today?” You guessed, judging from his intact suit but clear whiff of power about him.
Izuku scrubbed a hand through that riot of curls, exposing the reddened shell of a cold ear. “I only had to use blackwhip a couple of times,” he said as he shouldered the door closed behind him, the muscle of his thighs flexing enticingly as he stepped out of his boots.
You gestured at the pot of soup you’d left warming on the stove, and the veritable pile of crusty bread beside it. Warmth and carbs, exactly what you would have wanted if you were a pro hero fresh off a long day of patrolling in the snow.
Izuku’s eyes fixed on it with an obliging amount of interest, and he almost tripped over himself in the genkan in his haste to get to the kitchen. “I love you,” you heard him say, muffled through a mouthful of bread, heard the clatter of the silverware drawer and a bowl being placed on the counter.
You smiled and turned back to the book in your lap, a particularly dry, knotty text on robotic imitation learning that had had your eyes drifting closed for the better part of an hour. It was the last you’d need to get through for your Wearable Technologies graduate course, and something you were deeply interested in incorporating into your design practice. You could train a piece of equipment on how an individual pro hero moved and deployed their quirk, and use predictive modeling to deploy assistance functionalities within milliseconds if you got it right—such as immediate cooling in pro hero Shouto’s temperature vest the moment he ignited an arm.
The implementation was going to be so cool—but the theory was so mind numbing.
You felt the couch sink in beside your feet, and Izuku peered interestedly at the title in your lap.
“Introduction to Robotic Imitation Learning,” he echoed, and you could hear the note of excitement in his voice. You suppressed a fond smile, knowing he was already thinking through the same applications you had—he was just as much of a nerd as you were.
“Introduction to Snoozing and Napping,” you grumbled, turning back to your page. “There are only so many words on the Kalman filter framework a brain can handle before the human mind shuts itself down.”
Izuku hummed in interest around a spoonful of soup, propping himself up against your leg. The exterior of his suit was still cool from the outside, and he groaned with relief from the warmth of your skin, even as you hissed at the chill.
You knew he wanted you to go on, so you generalized for him. “It’s an algorithm used for robotic motion planning—you not only take measurements of the thing you want to model but you account for uncertainties to predict the probability that something is going to happen.”
Izuku nodded, taking another spoonful of soup, gesturing for you to go on.
You summoned up the willpower to explain joint probability distribution, pleased when Izuku easily managed to follow—he’d always been a quick study, especially of anything that could be employed in the service of heroics. You’d long thought if he hadn’t been gifted his quirk, he would be an insane support engineer.
He managed to finish his entire bowl of soup in the time it took you to explain, and housed another two slices of buttered bread with the sort of alacrity you’d only ever seen in pro heroes and professional athletes, making you smile while you spoke.
His spoon clinked softly against the edge of the bowl as he set them aside on the coffee table, and he hooked his chin over your knees as you finished explaining. In the setting sun from your windows he looked especially lovely, the kind, angular planes of his face brushed in gold, softening the spots of his freckles.
His eyes were especially bright, the way they always were when something in particular had caught his interest, and he smiled at you again over the tops of your knee caps.
“I admire how smart you are,” he told you, in the simple, straightforward way he always gave out compliments. It was like a shot to the heart every time, and you could feel your face warm with the praise even after years of receiving similar compliments.
You reflexively flapped a dismissive hand. “Not smart enough to have internalized it all! I have mostly been falling asleep to it,” you promised him.
He tilted his head, a green curl falling into his eyes. “I know you won’t have a problem when you’re awake.”
You shifted your legs with embarrassment, and a long fingered hand came up to cup the front of your thigh, as Izuku turned more fully towards you. You could feel the warm, hard planes of his chest against your shins, the line of his jumpsuit’s zipper pressing insistently just below your knee.
“Gotta try to impress you somehow,” you joked, your skin prickling as Izuku’s fingers absent-mindedly drew a pattern across your thigh. You could feel the heat of his hand through the thin material of the leggings you’d lounged around in all day, the chill finally chased away from his skin now that he’d come inside and warmed up.
“You do impress me,” he said in his soft, gentle tone. Which made your cheeks and nose burn hotter.
You knew you did, and the steady faith Izuku had in the people around him was one of your favorite things about him. It still made you feel like a middle schooler with a crush to think about, though, the intensity of your feelings too much for one body to handle.
“I will study hard to live up to your faith in me,” you promised, unable to help the goofy smile you knew you were giving him.
Izuku’s chin shifted against the tops of your knees, and he pressed his mouth to the knob of your left one, leaving a smiling kiss. “Tell me more?” he asked, fingers still sliding softly over your thigh.
“I’ll read it to you as I go, then,” you said, turning back to the brick of a tome, propping it up more firmly on your stomach as you adjusted yourself against the couch arm. Izuku’s eyes watched you over the top of the pages, that emerald gaze tracking your face closely.
“‘The algorithm works via a two-phase process: a prediction phase and an update phase’,” you began, trying to turn your attention away from Izuku and back to the text. “‘In the prediction phase, the Kalman filter produces estimates of the current state variables, including their uncertainties. Once the outcome of the next measurement (necessarily corrupted with some error, including random noise) is observed, these estimates are updated using a weighted average, with more weight given to estimates with greater certainty.’”
Izuku’s long fingers traced firmer lines across your thighs, almost like he was taking notes. He layered another kiss along the line of your knee, eyes glittering at you as you read.
“‘The algorithm is recursive,’” you continued, “‘It can operate in real time, using only the present input measurements and the state calculated previously and its uncertainty matrix; no additional past information is required.’”
You almost jumped as Izuku’s mouth trailed lower, into the space between your knees, leaving kisses along your inner thigh. His fingers gently pulled one thigh away to make space for him in between, and you cleared your throat, trying to return to the text at hand.
“‘Optimality of Kalman filtering assumes that errors have a normal–that is, Gaussian–distribution,’” you read on. “‘The following assumptions are made about random processes: Physical random phenomena may be thought of as due to primary random sources exciting dynamic systems. The primary sources are assumed to be independent gaussian random processes with zero mean; the dynamic systems will be linear.’”
Izuku let out a soft breath, insinuating himself further between your thighs. Your own breath came out a little uneven as he bent over you, mouth tracking dangerously towards the inseam of your leggings.
You paused, but Izuku fixed you with a look of his slightly-darkened eyes. “Please—keep reading,” he said, his tone a little lower than it had been a minute ago.
You swallowed in shocked understanding, skin tingling. You felt yourself nod, as Izuku’s fingers strayed to the waist of your pants, dipping below the band.
You let him slowly peel your leggings down, your underwear with them, adjusting as needed to make it easy for him, even as you tried to return your attention to your textbook.
“‘Regardless of Gaussianity, however, if the process and measurement covariances are known, then the Kalman filter is the best possible linear estimator in the minimum mean-square-error sense,’” you quoted, nearly squeaking when Izuku pressed his mouth to your hip, his curls tickling the skin of your belly. His hands gripped either side of your thighs, palms square and rough against your skin, and you tried not to shiver with the feeling.
“Um—‘Although there may be better nonlinear estimators’,” you said, then nearly jumped out of your skin when Izuku pressed his mouth to the core of you, only the strength of his grip stopping you from accidentally kicking him in surprise.
“Oh my g—uh! It—um—‘It is a common misconception perpetuated in the literature that the Kalman filter cannot be rigorously applied unless all noise processes are assumed to be Gaussian,’” you managed, before your cut off into a groan as Izuku layered a hot, sweet kiss over you, tongue dipping carefully between your folds. “Ah-–Izuku—”
Izuku petted a thumb gently over the top of your thigh to show he was listening, even as he swiped his tongue over you again, a long, firm stroke that had your thighs flexing in his hold. He laved over your clit, sucking ever so slightly, and your grip almost tore the edge of your textbooks as it tightened.
“Keep going,” he urged briefly, then did it again, punching a groan out of you.
“Extensions—oh—‘Extensions and generalizations of the method have also been developed, such as the extended Kalman filter and the unscented Kalman filter which work on nonlinear systems,’” you read on, voice shooting up nearly into a squeal when two of Izuku’s long, firm fingers pressed into you, as his mouth moved over you again.
“Ah! Oh my god—the—um, the basis—-” you said, breath growing short. Izuku’s fingers unerringly found the spot inside you that made you twist in his grip with the ease of long practice, and his jaw worked as he kissed you so shockingly filthily. You could feel something already starting to build up behind your navel, a fluttery lightness, an insatiable insistence on more.
“‘The basis a hidden Markov model—oh, fuck—such that the state space of the latent variables is continuous and all latent and observed variables have–ah!--Gaussian distributions,’’’ you recited, your voice tripping up further into a register that sounded more like begging than reading.
Izuku’s fingers worked you, long and thick and perfect inside you, as his tongue drew unrelenting circles around your clit. Stars seemed to spark in your vision, and your eyes squeezed shut, losing your place on the page as your hips flexed into his face. You felt suddenly very floaty and lightheaded, and not at all in a position to keep going.
Still, you tried to refocus your attention.
“‘K–Kalman filtering has been used successfully in—oh—multi-sensor fusion—ah, ah!--and distributed sensor networks–fuck, please, Izuku—to develop distributed or consensus Kalman f-filtering,’” you said, your tone nearly a cry.
Izuku groaned softly, sucking gently as his fingers curled inside you. It made your veins spark under your skin, your legs shaking in Izuku’s hands. You abandoned your grip on your book to seize the arm of the couch, clawing desperately at the fabric.
“Please, Izuku,” you cried, hips bucking towards his mouth.
The book tumbled off your stomach but you hardly noticed, gaze refocusing on the way his eyelashes fluttered as he licked you. His fingers played gently within you, a maddening press that was simultaneously too much and not enough, and his other hand came up to slide under your sweater, plucking gently at your nipple.
You lost yourself to the feeling—caught between the mind-melting curl of his fingers, the delicate suction of his mouth, and the careful pinch of your nipple. A delicious heat curled through you, waves of unbearable pleasure, and you could hear yourself babbling nonsense—garbled syllables of Izuku’s name, and every entreaty you could think of, a hundred thousands mores and oh pleases.
Izuku abandoned your nipple to pull you more firmly against him with a strong arm curled under your thigh, pressing you even harder into his mouth.
You muffled a scream in the sleeve of your sweater as he sucked you harder, tongue laving over you in loving strokes. Only his terrible strength held you down as you writhed beneath him, and then his fingers twisted in a way that had your vision whiting out—and you were suddenly thrown out over the edge of your pleasure.
Izuku licked you through it as you squirmed and begged and cried out his name, your climax seeming to last for eons.
You were panting hard when you finally slumped into the cushions of your couch, the ceiling seeming to swim in and out of focus before your eyes. When you gained enough control of your body again you looked down at Izuku, finding him watching you with a satisfied, almost shy curl to his mouth.
“You’re beautiful,” he told you, emerald gaze glittering with sincerity. “You’re so smart.”
Impossibly you felt your heart swell with even more love for him, and you seized his shoulder, dragging him up over you so you could kiss his mouth. The taste of yourself on him was embarrassing yet thrilling, and you petted a pleased hand through Izuku’s wild mess of curls as you kissed him.
“Well you are amazing,” you told him, swiping a thumb over his cheek fondly, smoothing over his freckles. A gorgeous watercolor of pink washed over his cheeks and nose at the proclamation, and you could hear his fingers flex in the cushion beside your head.
The sight of him flushed and waiting over you like another small something inside of you, like a pilot light, and you let your mouth pull into a wry grin.
“I hope you know I learned nothing though,” you said casually, your plan for your next steps already forming in your head. You let a hand trail carefully down Izuku’s flank, tracking towards his waist. “I think maybe I might need a few rounds for it to really sink in.”
Izuku’s ears went red against the green of his hair, and you felt your smile widen. “Maybe you could read it to me this time?” you asked, guiding him to roll under you, retrieving your book from the floor as you did so.
You settled yourself on the tops of Izuku’s thighs, feeling the hard press of him against your core, as you placed your textbook into his waiting hands.
Izuku’s answering smile was all the permission you needed. You directed him to start from the beginning of the chapter, and he did so in that soft, lilting tone of his you so loved. And then your fingers trailed up to the zipper at his collar.
It was time to return the favor—wholeheartedly.
REFERENCES: Kalman Filtering (Wikipedia) I took the passages our Reader recited from here because I do not actually understand Kalman filtering at all and could not organically come up with feasible text for her to read through. Sorry in advance to the author of this page lol.

Is it the same reader with mental health issues who divorced Bakugo, but he still hangs around? I'm v curious to know about her
the very same <3
tw: suicide
its... hard for him to explain to his friends and family. Whenever he starts, it makes him seem heartless.
The two of you had been sitting in silence since you had come home, television off, lights dimmed. Dinner was sandwiches from the store downstairs, the only place open so late at night. You picked at the bread, spreading it across your plate instead of in your mouth. His food is long gone, but he sits anyway, silently fuming.
"My throat hurts," you say and the string inside him snaps.
"Yeah. They jammed a fucking tube down your throat, of course it fucking hurts." He pushes away from the table so hard that the plates rattle. There should be a sorrow inside him, or an empathy, but the only thing his brain can produce is this seething rage.
You, on the other hand, give nothing. "Don't yell at me."
"Oh, I'm gonna fucking yell." He paces along the same kitchen that you used to dance in on Satueday mornings, when the sun hit just right. No, he isn't yelling. Not yet. "This isn't even the fucking beginning of me fucking yelling at you."
"I'm tired, Katsuki."
Of course you are. The hospital was so bright and loud and your body went through so much-
"Oh, you're tired?" Now, he's yelling. It's the kind of shit that the neighbor'a will complain about. "You weren't the one scrubbing blood out of the fucking bathtub last night."
You adjust your sleeves down, as if he hasn't already seen. As he if wasn't the one to-
"What the fuck were you thinking?" Bakugo knows he's being too harsh, but it won't stop flowing out of him, like his body is a sieve and awfulness just seeps through him. "You wanna die that bad? You want to leave me that bad?"
He prefers the days you fight back. Once, you threw a plate so hard that it cracked the tile and shattered so hard it cut both of your legs. At least then, there was life in your eyes.
"I'm tired," you repeat.
"Get help." He's so loud that it makes his voice ache. "Or I'm walking out that fucking door and never coming back. I'm serious. I'm so fucking serious."
Your expression doesn't change.
"I'm so tired, Katsuki."
reminder that being against ai also means being against character.ai and not using character.ai and not interacting with character.ai
i've never talked to chatgpt i've never talked to character.ai i have no interest in talking to a chatbot even if it's fun or based on my comfort character. if we want companies to stop using ai we need to tell them we aren't going to interact with it - so don't.
don't talk to robots. full stop.
