The first time you meet him is a blur. You just so happened to be staying at the same hotel that night— you were on your first business trip while he was away for the nth time for a game. You wanted to enjoy the last night of your trip and treated yourself to a drink at the hotel’s bar. It doesn’t take long until Sayomi’s father spots you, goes to sit obnoxiously close to you, and proceeds to ask you what you were drinking, even though he already knew martini was. 

You’d think he couldn’t get any more cocky than he already is now, but that’s all what Sukuna was when he was 24 years old. He just couldn’t wait to tell you what he did for a living, and accused you of staring at his thighs to get that conversation rolling. 

“I don’t mind you staring at ‘em, just means I’ve been training right.”

You didn’t ask him to elaborate on that like he thought you would, so he eventually just told you. 

He also eventually convinced you to come back up to his hotel room with him, where he also couldn’t wait to show you how big his dick was and how good he could make you feel with it.

You really don’t remember much except for the way he kept pulling your hips back to meet each thrust and how that alone made you cum more times than you ever have in a single night. And the way he moaned— god it was sexy. So low, so smooth. He’d stare at you with half-lidded eyes, watching his cock split you open and disappear inside of you, in a complete trance over how you took every inch he gave you. 

That was the night he realized he’d fuck you forever if he could, and he’d be lying if he said he didn’t feel that way anymore. 

It obviously didn’t last forever because that’s just not possible, but he did want your number. One could imagine his disappointment when he woke up the next morning and realized it was a fucking pillow that he had his leg thrown over, not the woman who’s guts he spent hours rearranging the night before. 

Fate decided to do its thing though when he spots you on the same plane back home, where you happened to be sitting right next to him in first class. 

No, you never met him in the bathroom for round 2. He tried, believe him, but he understood why you rejected him when he noticed you walking with a slight limp as you got off the plane. He did get your number though, which will always be worth so much more than just a quick fuck in a cramped bathroom of an airplane. 

He especially feels that way whenever he looks at his little girl that he’s known for over a month now— should be 10 months, but it seems to be just him that’s counting with how normal everyone is about this. 

Everyone except for the woman that’s been blowing up his phone, despite upping the number of date nights they have every week. 

He’s been wondering what his 24 year old self would think about all of this. 

Probably happy at first, after finding out the kid he has is with you, then confused after finding out you two weren’t together. Maybe even hurt after finding out how things ended. 

“What did we even do to her?” 

“I don’t fuckin’ know.”

He gets a knot in his stomach whenever he thinks about it long enough. This strange feeling of impending doom begins to wash over him, even when the worst has already happened. He’s constantly having to remind himself that he’s okay and everything will be fine, then he sees you and realizes that you’d slap his hand away if he ever tried to reach out to you. 

Gone is the girl who’d happily lean into his touch— she literally vanished into thin air for him. 

His phone vibrates after letting a call go to voicemail, and finally checks it. 

Yor: Are you sure you can’t leave early? We’ve been wanting to go to the concert for a while now. 

Sukuna: I really can’t, I already told you Yomi’s got an appointment. She’ll probably be in a bad ass mood after, you know how sensitive she is. 

No, she doesn’t know, she’s never met the kid.

He didn’t specify what kind of an appointment it’d be, but he’s sure getting an ear piercing would be a worse experience than getting flu shots or whatever they give to babies.

Truth be told, he just doesn’t wanna be away from her. He spends more time at your house than he has at his own and will probably stay with you both up until her bedtime tonight—ingraining it into his daughter's head that he’ll be there for her every time she feels pain.

She won’t remember it, but it’ll become a subconscious thing. She’ll eventually just know that he’s someone she can go to if she’s not okay. 

You two decided to go in the same car and meet your mom at the fancy piercing shop she suggested, more than ready to spend a fortune on her granddaughter's first pair of earrings.

“Are you excited, sweetie?” She turns to you and asks

“I’m just worried about how long she’ll be sore for.” 

“Just give her some Tylenol.” Your mother simply says, waving off your concerns.

“Fuck, I should’ve called her pediatrician and asked if that was okay.”

“Honey, we used to line your gums with vodka whenever you were in pain from teething, a little bit of baby Tylenol isn’t going to hurt her.” Your mother reveals and Sukuna immediately steps away from her, to which she immediately scoffs at. “It was a different time, okay? I’m sure your parents did the same to you.” 

He ignores her and turns to you, “call them and double check.” 

He met your parents a couple weeks ago and so far it’s been good. Their relationship is very relaxed. You weren’t sure what to expect since it was you that decided to be a single mother, but they were pleasantly surprised to find out who exactly it was, with your father muttering “I fucking knew it” under his breath. 

You ignored that comment. 

They’re just glad their grandchild’s father isn’t a bum, which also confused them more as to why you did what you did. 

“I kinda wanna get mine pierced with her.” Sukuna mentions while rubbing her little earlobe between his fingers. 

“Seriously?” 

“Yeah. I feel like she’d cry less if she saw me getting it done first.” He explains his little last minute theory. There’s also no doubt in his mind that they’d look good on him, but that’s something he keeps to himself. 

“Guess it won’t hurt for you to try.” 

He turns to your mother with a shit eating grin. “You tryna buy me a pair of earrings too?”

“Never in my life would I do such a thing,” she laughs a little too hard. “We all know you could buy this whole store and it wouldn’t put the slightest dent in your pocket.” 

“Rude.” He complains boyishly while looking at which diamond studs he wants. “It’s the thought that counts y’know.”

“I’ll try to keep that in mind during christmas time. Let’s hope I forget how much Google said your net worth was by then.” Your mother quips. 

“Tch– whatever.” He clicks his tongue and chuckles, then turns to you. “Do you want anything?”

“No, I don’t see anything I like that I don’t already have. Thank you though.” You say after taking a brief look at what they had to offer. In the end you decided it’s probably best if he doesn’t buy you anything, even though there was a necklace in the corner of the glass display that you really liked.

One that he was more than capable of buying.

Soon enough, it’s you holding Yomi while you both wave at her father who’s sitting across from you too. For once, you find yourself appreciative of Sukuna and the lengths he is willing to go to in order to make your daughter's life slightly easier.

It was a smart idea, you could see why he thought that her seeing him getting it done would help the process.

Except when the gun goes off, she flinches and her eyes grow wide in horror as she sees the diamond stud that the little device left on his ear. 

She started crying before the piercer got to Sukuna’s second ear and cried even harder when he actually got the second piercing. You both ultimately decided that today just wasn’t the day you’d get them done— you might not get them done ever given how traumatized the experience of just watching her dad getting piercings has left her. 

The three of you were supposed to go out for lunch with your mother right after, but you also decided that it was best to go straight home. She’s having one of those meltdowns where it’s best to go home and put her to sleep, scheduling the appointment at noon probably wasn’t the best thing to do since it clashed with her nap time. At least she’ll sleep well, you know you do whenever you sob as hard as she is right now.

You ended up having to sit in the backseat to comfort her, which was fine until she decided that she was going to string out the tears, because getting attention from mommy is nice. 

“oohuhuhu,” she whimpered in her little voice, it was so forced— barely any emotion behind it and Sukuna bursts out laughing because of it.

You end up having to look away too, not wanting her to think you were making fun of her. But it was already too late as tears started to well in her eyes again from feeling embarrassed. 

Lately, it’s been him who’s been trying to coddle her whenever she’s in one of her moods. It actually works half the time— something that’s even surprised your parents when they came over the other week and watched him successfully calm her down. 

Today’s not one of those days, she keeps turning around and looking at you— wanting for you to come get her. Sukuna tried turning around so she couldn’t see you and she just stuck her little hand out to the side of him, reaching out for help. At that point you started to feel bad and ended up taking her, not missing the slight pout on Sukuna’s face when you did. 

“Sukuna.” 

“Hm?”

“Can you look away?” 

“Oh right, my bad.” He doesn’t mean it. You throw the baby blanket over you and let him know his eyes were free to roam again.

His eyes go straight to Yomi’s little feet that were sticking out of the blanket and joyously kicking around because she finally got what she wanted, once again reminding him how much of a brat she is. “Are you sure she didn’t get her attitude from you?”

“No, my parents said I was the easiest child ever.” You laugh at how in denial he is of being the one to pass down the ‘tude to her. “Even Jin said she gets it from you, you just didn’t hear him because you were too busy arguing with Yuji.”

“Don’t believe a word Jin says,” he says, taking a seat on the sofa across from the one you were sitting on. “He was a thousand times more sensitive than this one.”

“I’m sure.” You say and leave it at that. After hearing about their parents dying when they were just 18, you try not to talk about anything that would lead to a conversation about them. You’re only cautious about it since Sukuna’s never brought it up before. And aside from sharing a child together, you two just aren't that close. 

“How long are you planning on breastfeeding her for?” He nods at Yomi when he asks, or your tits, you’re not sure anymore. 

“I wanted to be done by the time she turns one, but that’s a month away and I just don’t see that happening.” You sigh, starting to get literal war flashbacks of when you tried to stop. “I tried weaning her off right before you came into the picture and I lost so much sleep that I started seeing shadow figures.”

“What the fuck?” His face twists in disbelief. 

“Yeah.” You wish you were kidding, that was the worst week of your life. “She’d take her normal naps during the day, then she’d cry all night. I had to have my parents come help. I slept for like 16 hours and went back to breastfeeding her.”

“I can always watch her for the night if you wanna try to stop again.” He suggests, it doesn’t surprise you, he’s been like that one guy from the movie Holes. 

I cAn hELp wiTh thAt.

Very sweet, but you can’t help but feel like he has an underlying motive sometimes. 

“Maybe. I thought about trying again when she’s 18 months old.”

“You mean a year and a half?” He tries to correct you. He thinks he might actually lose it if you say she’s 24 months old when she turns 2.

“Same shit.” You roll your eyes at the man. 

“Okay.” He says sarcastically. “The season starts again around that time though, so it’d probably be better if you do that before then.” 

“Oh yeah huh?” He’s been around so much that you almost forgot that he travels half of the year. 

He used to fly you out a lot when you two were messing around with each other. This was back when you had the energy to hop on a flight right after work on Fridays, then get ready for work at 3 am on monday so you could go straight from the airport to work. 

You’d never do that for anyone, ever again. It was so much work now that you’re looking back. There was one point where you did that for nearly a month straight. You just had to stop, but by then he only had a couple weeks of the season left, so he didn’t seem to mind when you tapped out on him. 

“Do you think you two can travel with me for a bit once the season starts?” He asks in a low tone, it’s almost as if he’s nervous to ask. 

“I’m not sure. It's doable since I work from home, but it’s hard traveling with kids.” You hesitantly say. You don’t really travel all that much with her anyways, the thought of being far away from home almost makes you nervous. 

“Well, think about it. Some of the guys on the team are married with children and they bring ‘em along for at least half the time. I’m sure accommodations can be made for you two, maybe even pay for a nanny if you need the help.”

“I will, I’ll let you know in a couple months or something.” You say, before you both are interrupted by his phone ringing again for the third time since you’ve gotten back to the house. 

“You can take phone calls in front of me.” You let out a light laugh. He thinks you don’t know, but you are very aware of how much his girlfriend calls and texts him. 

He lets out a deep sigh while looking at the phone screen, it ends up going to voicemail again, but at that point he’d rather not keep her waiting and calling and waiting and calling.

“It’s probably something important, so I’ll just take it outside.” He mutters before excusing himself and stepping into the backyard. 

By that point, Sayomi’s fast asleep, so you end up sending Sukuna a little text letting him know you’re going to be in the nursery with her. You try not to think about the fact that you heard a couple yells coming out of the backyard as you walk up the stairs. You shut the door too so you don’t have to listen to him fighting with his girlfriend for like the hundredth time that week. 

You set Yomi down in her crib and take a seat in the rocking chair next to it, letting out a little yawn and rubbing the day away from your eyes. Sucks that Sukuna had to take a phone call, you were just about to ask him if he could watch her while you take a little power nap, you don’t get to do much of that anymore.

Your own phone buzzes, but instead of a call, it’s a text from Suguru. 

[11:05 a.m] Suguru G: How’s your morning going?

[01:11 p.m] Suguru G: Just remembered your daughter was getting her ears pierced today, just wanted to ask how it went!

[01:11 p.m] You: Oh my god I never even saw your text from this morning! Sorry about that. And she didn’t even get them pierced. Her dad thought it might’ve helped if she watched him get his ears pierced beforehand, but it ended up scaring her lol

[01:12 p.m] Suguru: LMAO

[01:12 p.m] Suguru: You guys traumatized her

[01:13 p.m] You: I know, I felt so bad! But I think she was just tired too, she woke up kind of early this morning. 

[01:14 p.m] Suguru: Probably. Is everything okay now?

[01:14 p.m] You: Yeah, she’s finally taking a nap, she needed it lol

You hear a little knock at the door and Sukuna comes in right after, walking up to the crib. Except instead of looking at his daughter, he was looking at your phone in your hands— looking like he was about to ask who you were texting. 

And he was extremely close to asking, mainly because he has a habit of starting more fights when he’s in a bad mood, but this time he practices some self control. He already knows it was fucking Suguru anyways and he’d rather not get into all of that when he’s already got other shit to deal with right now.

“I gotta go,” he whispers to you. His hairs slightly disheveled, looks like he’s been pulling on it or something. He leans over the crib and gives Yomi a couple forehead kisses before standing back up at full height. “I’ll see you tomorrow.”

“Okay.” You whisper back and do a little wave before he gently closes the door.

Even with the door shut and him trying to keep his voice down, you can still hear him suddenly snap and say something along the lines of “I already said I was fuckin’ coming” after picking up the phone, again.

notes: i'm hoping you guys are enjoying the story so far!! seeing the theories and thoughts make me giggle and kick my feet like a little slut, i'm hoping to get back to them very soon!!
