"Guess what day it is today."
Sukuna glanced over at you. He was working out on the lounge floor while you were on the phone. He'd figured out a few minutes ago that you were talking to Satoru.
"What? No!" You laughed. "It's mine and Sukuna's anniversary!"
Sukuna stopped at the peak of a push up, eyebrows furrowing. For a split second, he was unsure if he had missed some social cue along the way that should have told him he was courting you. In this modern age, relationships moved much faster than he remembered from during his lifetime. Not that he'd had much experience courting back then, either. He was too busy murdering everyone he saw to bother with anything more personal.
"Our meeting-a-versary!"
Sukuna sighed and went back to his push ups. Phew. He was grateful for that. Not that he would have minded that revelation all that much. He doubted it would change much about your relationship anyway.
"Our dynamic is not weird, 'toru."
Sukuna sat up and leaned back on his hands, chest rising and falling as he caught his breath. Your dynamic kind of was weird, though. He knew you knew that. Both of you tried pretty hard not to think about it. There was more leniency from the others with him, but not very much. You were still expected to be together all of the time. That meant that, apart from the rare occasions you'd managed to convince Sukuna and someone else to coexist for a few hours so you could go do something private, you had just been together. Sukuna knew you better than people that had known you for years, and you knew things about him that nobody would ever know.
"Ugh, do you have t- No, we don't!" You crossed your arms, pouting at your phone as though Satoru could see you through it. Sukuna watched you with a tiny smile. "What? Well- No, I mean, we do still share a bed, but- No, it's not-" You let out a groan. "Satoru, if you say one more thing about 'kuna, I'm going to hang up the phone." There was a brief pause. Then you leaned forward and hung up. You scowled.
Sukuna cleared his throat. He always liked how he could get your attention so easily now. Not because it made him feel powerful, but because it confirmed that you did care for him like he cared for you, despite the singularity of your situation.
"More questions?" He asked, as though he hadn't been eavesdropping the whole time.
You hummed. "Yeah. They're all so nosy. You'd think by now they'd have.." You trailed off, unsure of how to finish that sentence. You knew why people had so much to say about your relationship with Sukuna. So did he.
"Learned not to ask?" Sukuna supplied.
You nodded, standing up and pulling a water bottle out of the fridge. "Exactly. Even if they do think it's weird, it's our business, right?" You walked over to him, dropping the bottle in his lap.
Sukuna opened it and chugged half before he stuck his hand out. You helped him up. It was more of a symbolic help because you couldn't shift his body if you tried with all your might. You didn't mind, though. He let you do it and that meant something.
He nodded in agreement to your words, sauntering towards the bathroom. "Should tell them all to fuck off."
You laughed. "Why is that your solution so often nowadays?"
"Because I got him to lower his infinity one time and you still won't let me near him." Sukuna shot you a pointed look, one that was meant to say 'let me beat him up' but really said 'you should stick up for yourself more.' And then he was closing the bathroom door.
You walked into the bedroom, changing into your pyjamas and then settling into the pillows. Satoru's words weren't anything new, but they still rattled around your brain.
You knew it was strange for you and Sukuna to have never stopped sharing a bed. His funds had been in your bank for a long time now. The number was so high that you literally couldn't fathom it. You could've bought a bed. You could've bought a million beds made of gold. Sukuna should've insisted on it; he was the King of Curses, he shouldn't have been sharing a bed with a mere sorcerer. Especially not because of an agreement that was made all that time ago, which barely crossed your mind nowadays.
But you still woke up every morning intertwined. Usually, he was on top of you, his body draped over yours in a way that was simultaneously pulling you closer and keeping anything from disturbing you. And you liked the closeness, just like you knew he liked it, even if neither of you had ever said so.
Sukuna finished in the shower and dried himself off, padding into the bedroom in his robe. He turned off the light and climbed into the bed without a word. He rolled onto his side, reaching out until his hand found your body. His fingers dug into your waist and he gave you a tug towards him.
"Mm." You hummed and shuffled closer, letting him pull you flush against him. His body shifted so that he was partly covering you. You fell asleep.
Nothing disturbed him until the middle of the night. Sukuna opened his eyes enough to see that it was still dark and then snapped them closed again, moving to pull you closer. When he realised his arms were empty, a genuine sense of panic set in.
He took a deep breath, barely stopping himself from lashing out at the closest thing. Blind rage wasn't his style these days. He slowly rose to his feet and made his way through the house, eyes roaming the darkness until he saw you.
You were sitting on the couch, very still. You were nestled into the corner and you looked dazed, but clearly upset. Sukuna walked over and sat beside you.
For a moment, he was unsure of what to do. Even after all this time together, those few minutes before and after sleep were the only ones that held any kind of physical affection. Besides hitting each other, neither of you ever really showed it. Even then, it was usually him hitting you. He liked it, because he liked how you always reacted and he liked the reminder of how he'd learned to soften himself a little so that he could be playful with someone.
When you shuffled over to him and curled into his side, he was surprised. Surprised that he hadn't had time to think of what he was going to do, surprised that it was you that initiated the contact. Surprised that you wanted it.
His hands found your hips and he effortlessly lifted you up, resting you in his lap. His strong arms wrapped around you. He felt you stiffen for a second, just as taken aback as he was by his actions. Then you nestled your face into his neck and held him back.
Sukuna held you in silence for a while. He knew that quiet contact was what you were seeking, so he let you have it. He found himself strangely grateful that he could offer this comfort to you. Knowing someone intimately enough to know what they needed wasn't something he'd ever seen for himself before he knew you, let alone being trusted enough to actually implement it.
"What's wrong?" Sukuna murmured in your ear after a good few minutes had passed.
You sighed, leaning back so that you could see him but stay in his lap. "I can't sleep."
"Why?"
"I found out there's a secret execution out for both of us. I-I was going to tell you in the morning."
Sukuna very nearly laughed. Almost. "That's it? That's all it is?"
You looked at him completely seriously. "I'm not worried that you're going to die, I'm not stupid."
"What, then?" He asked.
You hesitated, then muttered, "I'm scared that they're going to turn their backs on us, and then all of this won't be worth anything to you, and you'll toss it all aside- toss me aside- and I'll lose you. That the agreement won't be important anymore and then none of this time together will matter."
Sukuna was stunned. Genuinely stunned, just like he had been on that very first day he'd met you.
You really cared that deeply about him? And he'd really doubted that you did?
He forced himself to mutter some normal responses.
"I'll kill anyone that tries to touch you, let alone harm a hair on your head. You are stronger than those pathetic sorcerers that would dare to do such a thing. I will split the world into pieces before they get the chance. The entirety of the jujutsu world is nothing compared to the power that you and I hold. You have the force of an empire at your behest, because I will not turn my back on you."
Normal responses for him, anyway.
You listened to him quietly, looking at him as he spoke. Sukuna's words were always slightly alarming, but you'd learned to see the comfort in them. He never lied. You knew that, to him, his strength was the greatest thing he could offer you. And so it was the greatest comfort when he goes on his little murderous tirades the moment you present him with a new target.
In the face of your attentive quiet, Sukuna found himself drifting away from the topic slightly. "It truly astonishes me that, after all that you've done for the jujutsu world, it could still turn its back on you. You have sacrificed so much. I told you it wasn't worth it and that they didn't deserve your energy, yet you continued to prioritise their collective welfare over your own. This is the price that you get for that goodness." His voice grew an edge as he grew more and more angry. "You should be good. I admire that you're good. It infuriates me when that's thrown in your face. It's something I would do, why are those self-righteous sorcerers doing it?"
A look of genuine anger crossed your face. Sukuna stopped talking, unsure of what he said that would make you mad.
"No, 'kuna, that's not the kind of thing you would do," you frowned. "You would never do that. You'd be more inclined to kill me directly. You wouldn't stoop to that low of throwing my effort back in my face, by encouraging people that I know, friends, to kill me."
And then Sukuna was getting angrier. "Don't say that," he growled. "Don't you dare use words like 'kill' and 'you' in the same fucking sentence when you're speaking to me."
Both of you glared at each other like petulant children. Slowly, the silence lengthened and then shifted as you realised that neither of you were angry for an actual reason anymore. Your eyes met his and you realised that he'd come to the same realisation.
You cracked first. You always did when it came to things like this. Despite your best effort to keep pouting, a giggle broke free.
At the first sign of your smile, Sukuna's anger completely disappeared. He was so obviously delighted to see you happy that it made your heart hurt. His arms wrapped around you and he held you close, chin resting on your shoulder.
He was so grateful. Grateful, grateful, grateful.
Your arms wrapped around him too, as tightly as you could. Sukuna always liked it when you held him. That was why you always woke up with him in your arms.
But he only had to pull back slightly to know that you were still upset about the execution. He gazed down at you for a few seconds, and then made his mind up. He would love you. That would make you feel better, if he could just figure out which demonstration of his love was the right one.
When Sukuna thought about how he loved you, he didn't think about telling you in some romantic gesture: I've always loved you, my darling angel. He didn't think about sweeping you off your feet with a kiss, holding your trembling body against his as he pulled soft gasps from your lips. Both thoughts made him smile.
No, that wasn't what Sukuna's love looked like.
He had hold of your hips again. He stood up, with you still attached, then set you on your feet. His hand slid into yours and he pulled you into the kitchen. Without an explanation, he pottered around the small space, pouring out your current favourite drink.
Then, when it was safely in your hands, he found the phone and started to play your music, the songs that he'd noticed you listening to most recently. He watched you like a hawk as you gratefully sipped your drink. But, when you smiled at him, he shook his head.
He turned and switched the oven on, found the cookbook, and tugged you over.
"Bake."
You looked taken aback, but you could see that he was serious, even if you didn't understand why. Dutifully, you began to mix a cookie batter. Sukuna hovered behind you the entire time. When you slid the cookies out of the oven, he switched into his true form, giving you no time to adjust to something you'd only seen a few times in the whole year you'd been together, and sat down on the floor. You were pulled firmly into his lap so that you could comfortably eat your cookie near the heat of the oven.
He watched you, even when you finally noticed how fierce his gaze was and looked up. He let you feed him a piece of your cookie, letting out a pleased hum of approval. Sukuna smiled when that soft interaction made you more happy than the whole process of baking had.
But you weren't better yet.
Sukuna stood up, changing back into his normal form, but keeping you in his arms. He carried you into the bathroom and started to pour out a bath. When he noticed you looking for the soap, he caught your wrist and tugged you to his side.
"Don't do anything."
You were confused, but you did as he asked, watching curiously as he pulled out a small box from the top of the linen closet. "What's that?"
"I was saving it," he murmured, opening it and letting you see inside.
It was full of special shampoos, conditioners, soaps, and bath bombs. He was saving it only partly because he knew a time would come for them. Mostly because he had never figured out quite how to explain that he knew your favourite smells and what would work in your hair or with your skin.
He was so busy checking that everything was fine that it wasn't until he turned to you to ask you to check the water temperature that he realised you were looking at him with something in your eyes that he didn't think he'd ever seen before.
You didn't give him a chance to ask about it. You stepped up to him and gave him a tight hug. He could tell that you were putting as much force into it as you physically could, so he didn't laugh when he effortlessly held you tighter. He held you close until you tipped your head back to look at him.
"Will you help me?"
Sukuna nodded, fingers sliding to your collar. He unbuttoned your shirt deftly, then slid it down your arms. He folded it and put it on the nearest surface, then gently pulled your shorts down your legs. He set that down too. Then he was inhaling the scent of your hair as he leaned over you, his fingers unclasping your bra. He was bending slightly so that he could hook his fingers in your panties and pull them down.
In the back of his mind, it registered that this was the first time he'd ever seen you this exposed. It was the first time he'd touched you here, seen you there. But it didn't really feel like a first time. It felt like this was normal, like it wasn't a big deal for him to do this. Like you had always been his in this way, and he had always been yours in this way.
His warm hands were on you as you climbed into the bath. One on your hip, feeling the curve of your waist, and the other on your wrist, both making sure that you were safe and not in any danger of slipping.
He might have nearly laughed at the prospect of a secret execution coming close to harming you, but the idea of you hurting yourself normally plagues him every day. There've been hundreds of times that he's insisted he use his RCT on you for little scrapes that you've gotten. Hundreds of times that you've had the same discussion where he's insisted that you're careless with yourself and you've said you're just clumsy and he's called you a stupid idiot and you've shut him up with a bright smile and an I've got you to help, though, right?
Sukuna watched you warily as he let go of you. He waited as you slid all the way under the water, staying under for a few seconds before sliding back up. His hands were on your face before you even had a chance to lift your own, thumbs swiping away the water from your eyes and brushing your hair out of your face. When you looked up at him, face clear of water, Sukuna finally looked relieved. This was the thing that helped, then. This was the part of his love that would make you happier and less stressed.
But that wasn't enough for him. He wanted happy, not happier.
He pushed his robe over his shoulders, letting it hang around his waist. Then he walked around behind you, sinking to his knees on the tiled floor. Without a word, he reached for your head, silently insisting on doing your hair for you. Neither of you spoke for a while. He ran the shampoo and conditioner through, then began to brush your hair.
"You've gotten so good at managing it," you mumbled, eyes closed happily.
Sukuna grunted. "Managing what?"
"Your force. It doesn't hurt when you're doing something like brushing my hair, but it used to hurt when you even laid a hand on my arm."
He smiled, glad to hear you say it. He'd already known he had improved a lot, but it felt worth so much more to hear it from your lips.
He finished with your hair. The next step seemed obvious, but he had the awareness that, no matter how intimate this all seemed, he couldn't go further without murmuring something.
Quietly, he said, "I'll bathe your body now."
"Okay."
That soft, mumbled agreement made his heart swell. He rose to his feet and found your hand under the water, pulling you to your feet. You let out a soft protest as he made you stand up in the bath. His warm hands on your skin eased the chill almost right away.
Sukuna focussed incredibly hard. He had to make sure that he did this right, that he treated your body with the reverence he believed it deserved. That his soapy hands graced every part of your soft, blemished skin. That nothing he did hurt you.
And his intense concentration meant that he failed to notice the way that you were watching him again. This time, because you'd recognised the look in his eyes, and you were admiring the way that his hands looked against your skin.
"Happy?" You chuckled after a while. Your teasing voice broke him out of his reverie.
He looked up, smiling slightly. "Yes. Are you?"
"Mhm." You slid back into the water, letting out a content sigh.
Sukuna wasn't really surprised when your hand found his wrist and tugged. Nor, when your pretty lips parted with a soft question.
"Will you get in, Sukuna?"
He nodded. His hand slipped out of yours so that he could loosen his robe and let it fall completely. He nudged you forwards and then climbed into the tub behind you. Sukuna rested his hands on your hips, but he let you be the one to decide whether or not you slid back or not. When you did, he wrapped his arms around your waist and rested his head in your neck.
"D'you want me to wash you?" You asked.
His reply came out like an admonishment. "No, foolish woman. You're the one that needed comforting. Stop trying to do things for everyone else all the time. Be selfish. Have you no self-respect?"
He was lucky that you knew him and his favouritism well enough to just smile over your shoulder at him.
All of the times he'd thought oh, shit to himself converged. He stared at your content smile, at the soft way you looked at him. And everything aligned in his mind and, this time, he just said it out loud.
"Oh, shit."
You looked at him in confusion, then laughed. "What?"
"You're beautiful," Sukuna stated simply. "You fill the gaps that I can't fill myself. You're the one that's meant to be by my side."
When your smile broadened and you leaned back into him again, he didn't mind that it took you a while to reply. He didn't feel nervous. Sukuna knew for certain that you understood him and you understood the weight and sincerity in his words. He didn't have any fear that you were something he could lose this way. The only thing he could lose you to was death, and he'd already begun making sure that wouldn't happen.
When your reply came, it was all he'd really wanted to hear.
"'Sukuna?"
"Mm."
"I love you."
"I know. I love you."
"I know."

Your roommate Sukuna knows he’s sexy. And he also knows that gym memberships are expensive, and it’s so much more fun to work out at home where he knows you’re bound to walk in and catch a glimpse of him. And today that’s exactly what happened.
You walk through the front door of your too small apartment to find him standing in the middle of the living room in nothing but a pair of baggy sweatpants, his arms hoisted above his head as he holds massive dumbbells in each of his calloused hands. His body is coated in a thin sheen of sweat, tattooed skin flushed a light pink and glistening under the overhead lights as muscular arms lower down to his head. The tattooed lines on his shoulder blades contort as he raises his arms up in the air again, the muscles in his back flexing as he lets out a quiet grunt, broad chest heaving as he pants out harsh breaths.
He’s walking sex. Holy fuck.
It takes a moment for you to pick your jaw off the floor, and unfortunately for you (but very fortunately for him) his body turns to face you before you can collect yourself. Your eyes are wide and your cheeks are flushed a dark red, and he gives you a cocky smirk.
His voice sounds raspy and breathless when he speaks, “You’re home early.”
God, there’s no way he doesn’t know what he’s doing to you. You can’t keep your head on straight, mind wandering to how his muscles would flex with him on top of you, how he would be panting and groaning into your ear, how his voice would be so raspy when he says the nastiest things to you.
Is it a blessing or a curse to be living with him?
You do your best to keep your voice steady, turning your head away from the smug grin plastered onto his face, “Yeah it was, um, slow tonight.”
He lifts the weights in another rep, grunting out “Yeah?” His breaths are heavy and labored, “Nice and slow, huh?”
It’s a curse. You fear that your legs are going to turn into jello beneath you if you’re around him any longer. Your face feels like it’s burning hot as you hum out a rushed “Mhm” and nearly sprint up the stairs to your room.
You need to lay down, need to stop thinking about your hot roommate. You slip out of your work clothes and into an oversized t-shirt, crawling into your bed and burying your flushed face into your pillow.
It doesn’t take long for you to fall asleep, and it takes even less time for you to be woken back up to Sukuna knocking on your bedroom door. You faintly hear him asking “You alright?” from the hallway, and you groggily pull yourself out of bed to open the door to face him.
And now it’s his turn to feel flustered.
He can’t help but wonder if you’re wearing anything underneath that baggy shirt, imagine what it’s like to see you sleeping peacefully on your side in his bed, think about sliding his hands underneath your shirt and feeling your soft skin up against his body. But lately his thoughts have been growing beyond just wanting to fuck you, he wants to be close to you.
Sukuna has always thought that you were hot, hell, it was the first thing he noticed when he moved into your apartment. And he’s seen you in your sleep clothes probably a million times at this point, sleepless nights of you coming downstairs for a glass of water, lazy mornings on your days off when you’re eating breakfast on the couch, but every day it’s starting to feel more and more intimate.
It’s not just some kind of “what if I fucked them” thing to him anymore; he wants to hold you up against his broad chest, he’s wants to run his fingers through your hair, he wants to interlock his fingers with yours and crawl on top of you and- oh christ there he goes again.
Your sleepy eyes are looking up at him in confusion and he realizes that fuck, yeah I’m the one who knocked on the door, and that he should probably stop gawking at you and actually say something.
“Just wanted to check on you.” He rushes out, and then abruptly slams the door shut. He’s hoping that you’re too tired and out of it to realize how fucking weird that was, but he felt a blush start creeping up on his face and he would rather die than have you see him like this.
He slumps his back against the wall, letting out a deep breath and trying to steady his pounding heart, or at the very least blame that pounding heart on his workout and definitely not you. But he knows damn well that’s not the case, and he doesn’t know how much longer he can go without making you his before he absolutely breaks.
