After the Breakup (BNHA Headcanons)

*GIFs not mine*

A/N: Welp, I was going to write for more people but when I started for these two babes-for-characters I guess I just couldn’t stop🤷‍♀️. Not quite sure how these headcanons turned out but hey, hope you like ‘em! (Btw they get a lil saucy, but I’m just in that mood so y’all are just gonna have to accept them for what they are🤷‍♀️)

Bakugou Katsuki: 

Wants to ignore you 

Definitely the type to fold his arms and turn away when you enter a room or scoff when you talk to another guy

But when you walk away the guy is being given a glare that could put him six feet under

Acts cold to you--not exactly like how he did before he was interested in you, like how he calls everyone “extras,” but more so like he just sneers at you for no reason and rolls his eyes everytime you speak

Lil pomeranian boi just misses you really badly

But he hates the idea that you have that much power over him that you could draw him back to your side in a matter of seconds. It frustrates him how much he wants you back

At one point he’s tired of having nightmares of you leaving night after night--especially now that he doesn’t have you to comfort him after waking up in a cold sweat. 

So he’ll climb out of bed and stomp over to your door

And proceed to stare at it for about twenty minutes with his mind and heart running marathons

What does he say?

What does he do?

Would you be mad? Sad? Disappointed?

Or… would you even care that he was still in love with you?

It all becomes too much, and soon enough he just has to know

So he raises a fist to pound on your door loud enough to wake the entire floor

And the door opens before he even makes contact. 

“Katsuki?”

“YN.” Surprisingly, Bakugou feels all too calm at this moment, like he knows exactly what to say. 

“What are you doing here?”

A muscle in Bakugou’s chin twitches as he struggles to find the exact words. He wanted to make his point but he also didn’t want you to slam the door in his face. “I… Look. You told me that we should both move on and that I should get over you.”

“Katsuki-”

“But here’s the thing, YN,” when he takes a step forward, you take a step back and he physically flinches at the movement, “I don’t want to.” He shakes his head. “I don’t want to get over us and move on to other people. I don’t want to see you with other guys when I know I could make you happier. That I have made you happier.”

“Katsuki,” your face softens, “you don’t have to-”

“Don’t tell me what I don’t have to do, YN. I’m not letting you go, understood? Try to move on all you want, I’m not going to let you. I’ll scare off any man you even talk to if I have to-”

Two hands piled over his mouth shut him up instantly and you lean past Bakugou to glance both ways down the hall before yanking him inside your room. 

As soon as the door’s shut, you turn to him and shake your head with the smallest little smile. 

“Katsuki, you dumbass. I was just going to leave my room to give you the same lecture.”

“Huh?”

“You took the words right out of my mouth,” you cup his cheek, reveling in the foreign look of shock on the blond’s face, “so no need for anymore threats on guys I may or may not go out with… unless you’re really willing to go after yourself that badly.”

Relief floods through Bakugou’s body, warming him up with the thoughts that he didn’t need to worry about truly losing you at all--as it turns out, you agreed you were his just as much as he did. 

“So… we’re back together?”

“Yep, unless…”

Oh shit

“Unless what?” Bakugou froze under your touch and reached a hand up to secure your palm against his cheek. “What is it?”

It almost pissed him off that you were able to laugh so freely while he was in an obvious state of panic. 

“Well, I was gonna suggest break-up sex but judging by just how badly you want to get back together, it seems like that’s off the table.”

Oh. Oh you damned little thing. 

Such a fucking tease. 

“Nah,” Bakugou shook his head and before you knew it, you were being forced down onto your bed, wrists locked tightly above you. “You’ve got the right idea. Break-up sex tonight, and tomorrow we can make up all day long.”

Kirishima Eijirou: 

On the surface, Kirishima is the same old manly man everyone knows him to be

But his eyes no longer have that same glint

And that smile just always seems seconds away from faltering

His red hair seems less spiky than usual, and those bags under his eyes are just the biggest tell

Kirishima is broken. 

He’s not grinning and holding your hand as he walks into class anymore, escorting you to your seat with a perhaps almost overdone kiss. Instead, he almost slumps to his own seat, avoiding eye contact with as many people as possible. 

But the instant you step into the classroom, you feel it.

You sit in the front row, giving him plenty of freedom to watch you for the entire day.

Kirishima thinks it’s natural, it’s harmless. He’s just trying to get over an ex--everyone knows how hard that is.

But he’s just making things worse. He tortures himself by constantly standing to attention anytime you speak. Or anytime your name is mentioned. Or anytime someone who remotely looks like you walks by him. 

No, he’s not doing great at this “moving on” thing, and he knows that. 

But part of it’s because he just can’t believe that you’re not struggling to do it either. 

Kirishima knows none of those kisses and “I love yous” were lies. He knows you meant every single hug and smile you ever gave him. Every time you said you cared about him, he could see in your eyes that you meant it wholeheartedly.

So maybe you could see how he wondered why loving you was suddenly so painful. 

Because now you were broken up and all this love he had to give you had nowhere to go and nowhere to be. It was like the love he had for you was useless. 

Kirishima hated those words, that thought. That being in love with you for all those months was useless, and that it just needed to be flushed away. 

All those plans he had of being with you, becoming superheroes at one another’s side and raising a family together. Planning ahead so far to even name the bridesmaids and groomsmen of your wedding and the names of your children. 

The future house and the rooms of that house, how many there would be and what kinds they were. You needed a library, one he was all too ready to build for you and he wanted a mancave you would surely supply with snacks.

All of that was useless. 

But Kirishima didn’t want to think so. So he came up with a plan. 

And when you walked into class the next day, Kirishima sat in your assigned seat, and you knew you smelled mischief. 

“Eijirou… whatcha doin’?”

When Kirishima raised his eyes to yours, the corner of his mouth turned up just an inch. 

“Sitting.”

You purse your lips. “I see that. But you know you could do the same exact thing in your own seat, right?”

The conversation wasn’t exactly a spectacle--the only other people in the room were in the back of the class talking amongst themselves distractedly. No one would bother to interfere. 

“Well, YN,” Kirishima leaned back, “I kinda want to trade places for a day. I wanna sit in your seat and act all nonchalant, pretending like I actually wanted us to break up-”

You could hear his voice growing choked up and moved to stop him. “Eijirou-”

“-and you can sit in my seat and do as I do. Remember how happy we were and how much you said you loved me. And how I broke up with you anyway.”

It was cold, like the room had suddenly dropped a few degrees. The boy everyone thought didn’t have a single mean bone in his body seemed to flip a switch in himself, turning emotionless in the blink of an eye. 

For him to act like you never loved him almost hurt as much as when you broke up with him. In all honesty, you thought it was for the best at the time. You felt it would help both of you focus on your studies so that you could become better heroes than anything. 

You thought that’s what Kirishima wanted, and that you were doing what was best for him. But you were wrong.

It seemed all he really wanted was you--being a hero had moved to second. 

“Eijirou…”

So the question was did you want him just as badly?

“YN…”

Becoming a hero was the entire reason you came to this school, and was also the reason you broke off one of the best relationships you’d ever had. You’d thought you were making things better. 

But had it really helped anything?

“Eijirou, I…”

Your grades had actually dropped. Terribly. You couldn’t remember the last time you actually got quality sleep. 

And judging by Kirishima’s dark circles, he was suffering the same side effects. 

These weren’t the symptoms of withdrawal--they were just the signs of a mistake. 

So as you looked into Kirishima’s eyes, hard enough to see past all the barriers he had put up, you could see the same questions you kept asking yourself. 

Why did I ever think this was worth it? Why did I ever think this would help me be happy?

The answer was it didn’t. 

And trial and error was a pain in the ass. 

“Eijirou, I’m sorry.” Your brows drew together in regret as you lowered your gaze, reaching over to grab the hand Kirishima had tensed on the desktop. “Maybe… no. Breaking up was definitely a mistake, and I wasn’t even thinking of the shit I was going to put both of us through by doing that. I’m sorry.”

But just as his mouth opened to respond, the bell rang and twenty other students flooded in in a mad dash to get to their seats. 

Before you moved to claim Kirishima’s seat as your own, you made a split second decision that you hoped could display even a little of what you were thinking. 

Kirishima froze at the kiss, his eyes going wide as you tilted his chin up to give yourself access. His lips were soft, just as you’d dreamt about for the last five nights, and tasted like that damned chapstick he always wore. 

And when you pulled away, he tried to reach out to stop you but you stepped away from his desperate hands, instead navigating your way back to his desk. 

Kirishima was frantic, spinning in your seat to get a look at your blushing face while his own mouth stayed open enough to catch a couple flies. The second your lips quirked up into a smirk, he almost jerked back with whiplash. 

Fucking hell, she did not just-

“Okay class,” Aizawa slumped into the classroom with his usual cheerfulness. “I want you to take a look at-wait.” The teacher paused for just a second to take note of Kirishima’s back facing him and you just five seats away whistling and observing the ceiling with interest. 

“YLN, Kirishima, get back to your original seats for God’s sake. There’s no time for this.”

All too ready, Kirishima rose from your chair and made his way towards you with eyes unsteady and hungry. 

Tonight you would explain just what exactly you were thinking when you decided to break up with Kirishima out of the blue. I mean, you seriously almost gave him a heart attack. 

Directly after school though…

Kirishima caught your arm as you moved to walk past him and threw you a look that would stick in your mind for the rest of class. Just as fast, he released you completely and dropped into his seat, eyes locked on your every move as you slid into your own.

Oh yeah. Directly after school, he was going to make you pay for the pain you put his mind through with your body.
