dad!sukuna with yuji who learned to walk
mornings in your house are never quiet anymore. not since yuji had learned how to run.
it starts with the sound of small, uneven footsteps padding down the hallway, followed by the unmistakable thud of something—usually him—bumping into the wall, the doorframe, or occasionally just… the floor. there’s always a pause after, like he’s deciding whether it hurt enough to cry, and then...
“mama!”
you don’t even get the chance to sit up properly before your bedroom door swings open and a tiny body launches at you with absolutely no hesitation, all warmth and energy and zero sense of self-preservation.
“good morning, baby,” you laugh softly, catching him before he can fully faceplant into you, hands smoothing over his messy hair as he climbs all over you like you’ve been gone for years instead of just asleep.
he giggles, pressing his face into your shoulder, already babbling about something you can’t quite understand yet, words tumbling over each other in half-formed excitement.
from the other side of the bed, there’s a low, unimpressed groan.
“kid’s gonna break his neck one day,” sukuna mutters, voice rough with sleep, one arm thrown lazily over his eyes.
yuji immediately perks up at the sound of his voice. “dada!”
and just like that, he’s climbing over you to get to him, tiny hands grabbing at sukuna’s shirt, knees digging into his side with absolutely no regard for personal space.
sukuna hisses quietly under his breath when a particularly sharp elbow lands somewhere unpleasant, but he doesn’t push him off. doesn’t even try.
instead, his hand comes up automatically, large and steady as it settles at the back of yuji’s shirt to keep him from toppling over.
“watch it,” he mutters, though there’s no real bite to it.
yuji just laughs, completely unbothered, and pats sukuna’s face like he’s checking to make sure he’s real. “up,” he demands, very seriously.
sukuna cracks one eye open, staring at him flatly.
“…no.”
yuji frowns. thinks about it, then leans forward and presses his entire weight onto sukuna’s chest.
there’s a pause. “…alright,” sukuna exhales, defeated, dragging a hand down his face as he finally pushes himself up slightly, still half-trapped under a very determined toddler.
you laugh softly from where you’re sitting, watching the whole thing unfold, your heart doing that familiar, warm little twist it always does when you see them together like this.
because sukuna who’s rough around every edge, who speaks in low tones and sharp words, who doesn’t have a gentle bone in his body for anyone else is so… careful with him.
he acts like he’s annoyed, like this is an inconvenience, like he’s only tolerating it out of necessity. but his hands never slip. his grip is always steady.
his eyes, when they rest on yuji for just a second too long, are softer than anything he’d ever admit out loud.
“hungry,” yuji announces, like he’s just made a groundbreaking discovery. sukuna snorts quietly. “course you are.”
you slide out of bed, stretching slightly before walking over, pressing a soft kiss to yuji’s cheek and then, just as easily, to sukuna’s temple. he doesn’t react much, just glances at you briefly, but his hand shifts, resting lightly against your hip as you move past him.
“i’ll make breakfast,” you say, already heading toward the kitchen.
yuji scrambles after you immediately, little feet pattering loudly against the floor, leaving sukuna sitting there for a second longer than necessary. he watches you go, then exhales, pushing himself up with a quiet grunt before following, slower, less chaotic, but just as certain.wq
by the time he reaches the kitchen, yuji is already standing on a chair you pulled up to the counter, watching you with wide, curious eyes as you crack eggs into a bowl.
“help,” he says, reaching for the whisk.
you smile, guiding his small hands carefully. “okay, but gentle, yeah?”
behind you, sukuna leans against the doorway, arms crossed, just watching. he doesn’t say anything. doesn’t need to.
the soft domestic noise, the quiet laughter, the way you bend slightly so yuji can see better, the way he leans into you without thinking—it all settles somewhere deep in his chest, heavy and unfamiliar in a way that would’ve bothered him once.
now, it doesn’t. now it just feels… right.
yuji suddenly turns, spotting him again, face lighting up instantly. “dada! help!”
sukuna huffs, pushing himself off the doorway and stepping forward, large hands easily covering yuji’s smaller ones as he takes over guiding the whisk. “like this,” he mutters, slower than usual, more deliberate.
yuji watches closely, completely fascinated. you watch them both.
for a moment, everything feels still in the best way possible. soft, warm, full in a way that doesn’t need words.
because somehow in all the chaos, in all the sharp edges and rough beginnings you ended up with this.
and sukuna, who never thought he’d want anything like it stands there beside you, one hand steady over your son’s, the other brushing lightly against yours, like he’s not letting either of you go anytime soon.
