Chapter Text
Satoru is already sitting on the counter when Sukuna stalks into the bathroom with the little canvas pouch, the one that rattles softly with alcohol wipes and a syringe.
The mirror is fogged from his shower, steam frizzes the ends of Satoru’s hair and makes the blue of his eyes glow like a bad idea.
“It’s not a ritual,” Sukuna says, voice a rougher gravel than it used to be. “Stop sitting like a shrine attendant.”
Satoru grins and spreads his knees anyway, making space at the sink.
“I’m here for moral support and to make you blush. Strict medical protocol.”
“I don’t blush.”
“Mhm. Your ears?” He flicks the edge of one, and the tip warms under his finger exactly on cue.
Sukuna clicks his tongue and sets the pouch down.
He’s broader these days — shoulders chewing through t-shirts, that clean new weight riding his frame like it’s always belonged there, the faint shadow along his jaw refuses to shave clean no matter how close he goes.
He doesn’t comment on any of it, but Satoru notices everything and stores it like treasure.
Sukuna rolls the vial between his palms to warm it.
Satoru, who absolutely knows better than to talk during the draw, leans close enough that their hips bump.
“You know,” Satoru says, low and delighted, “every time you do this, you look more like the man who throws me through walls for fun.”
“You’d heal faster if you knew when to shut up.”
“Untrue,” Satoru says, already peeling an alcohol swab. “But noted.”
They fall into the rhythm anyway.
Sukuna lays out the supplies in neat ruthless lines, Satoru tears open the swab, then another when Sukuna arches a brow that says you touched that with your chaos fingers, didn’t you?
“Left leg today?” Satoru asks.
“Abdomen.” Sukuna lifts the hem of his shirt.
The scar-track of old battles crosses the hard plane of his stomach, new muscle pulls tight under Satoru’s gaze.
“Rotate,” he says, as if Satoru needs the reminder.
“Rotating.”
Satoru’s palm settles, wide and warm, just above Sukuna’s hip as he swabs in outward circles.
He shouldn’t linger.
He does anyway.
The pad of his thumb drifts over the cut of Sukuna’s oblique, a soft drag that’s nothing like clinical.
“Your skin runs hot.” Satoru murmurs, entirely unhelpful to the cause of efficiency.
“Because you’re close,” Sukuna says, glare sharp but unfocused, the corner of his mouth betraying him. “Hands where they’re supposed to be, Gojo.”
“Define ‘supposed to be.’”
“Not there.”
Satoru obediently moves his thumb half a centimeter.
“Better?”
Sukuna huffs, which is not the same as yes.
They check the dose together, Satoru’s chin hooked over Sukuna’s shoulder while Sukuna pulls the plunger with steady, practiced pressure.
Satoru swaps needles and taps the barrel with the pad of his finger.
“No bubbles. Certified by the Strongest.”
“Don’t start with titles.”
“You started with ‘King of Curses’ first.”
“King,” Sukuna says, dry as bone, “of telling you to focus.”
Satoru laughs, easy and soft, then his face sobers.
“Ready?”
“Obviously.” Sukuna plants his feet, breathes out.
He never looks away for this, it’s stubborn pride and something else too — claiming each change like he’s cutting a mark into a stone.
The slow drop to his voice.
The way people flinch when he growls in a hallway and the way his friends don’t.
The first morning he shaved and scowled at the little constellation of nicks and then smirked at himself in the mirror anyway.
Satoru’s palm settles again, steadying.
“Pressure,” he warns, and the needle slips in on the tail of an exhale.
Sukuna doesn’t even flinch, but his hand fists in the edge of the counter and Satoru feels the flex travel under his fingers — muscle, will, victory.
“Done,” Satoru says after he depresses the plunger, calm as a tide.
He withdraws, presses gauze to the spot, and his other hand — this is the part that makes Sukuna want to bite — slides from hip to lower belly in a soothing pass that is entirely unnecessary.
“Stop petting me.”
“Can’t.” Satoru’s voice goes fond. “You do this brave thing to take care of yourself, I get to admire you. House rules.”
Sukuna swats his wrist, a light slap that never pushes him away fully.
Satoru takes the hint and turns practical for the thirty seconds it takes to cap the needle and tuck it into the little red sharps container Sukuna insisted on getting instead of Satoru’s original suggestion of “this very safe cookie tin.”
“Date,” Satoru says, and uses a marker to write it on the tiny calendar taped inside the cabinet.
Each square has a messy star doodled in it from Satoru’s hand, some weeks, the stars share space with terse notes in Sukuna’s script — range day went better, voice cracked in meeting, Shoko laughed herself sick, shirt fits shoulders, don’t let Gojo stretch it.
He catches Satoru watching him watch the calendar.
Sukuna shrugs like it’s nothing.
“Keeps track.”
“Mm.” Satoru tosses the marker aside and leans in until their foreheads touch.
“I’m proud of you.”
“Don’t start saying sappy things. You’ll melt your last two brain cells.”
“Harsh for a guy who enjoys my brain cells on weekends.”
“Incorrect,” Sukuna says, but he’s closer now, gravity doing what it always does to them.
The scent of his skin is different these days, warmer, richer — Satoru has spent whole afternoons ignoring paperwork just to breathe it in from the curve of Sukuna’s throat.
“You’re staring,” Sukuna says.
“You’re easy to stare at,” Satoru says, honest as a blade.
He drags the pad of his thumb over the line of Sukuna’s jaw, over the scruff that will be a beard soon if Sukuna lets it.
“I like this.”
“It itches.”
“I’ll kiss it better.”
“Absolutely not.”
Satoru kisses him anyway, smiling against the small sound Sukuna makes when their mouths fit.
Sukuna bites his lower lip on principle and Satoru hums in approval like that’s what he wanted all along. It’s not a deep kiss, it’s something slow and smug and satisfied, like the moment after a clean hit in a fight when both of them are grinning because finally, finally, someone can keep up.
Satoru breaks away first and rests his mouth by Sukuna’s ear.
“You want the sticker?”
“There is no sticker.”
“There could be. Gold stars. Tiny tigers. A sheet of ‘World’s Handsomest Menace.’”
Sukuna’s ears betray him again.
“I will burn your sticker collection and salt the ashes.”
“So you admit we have one.” Satoru’s hands — disastrously, purposefully — slide under Sukuna’s shirt and settle at his waist, thumbs curving into the front of his hips.
“Just so we’re clear— may I?”
The question is soft and normal, the way Satoru always folds consent into their orbit like it’s muscle memory.
Sukuna’s answer is an irritated sound that means yes and hurry up.
Satoru’s palms travel in slow lines, feeling what’s different and what’s always been true.
The muscle. The heat. The way Sukuna stands taller even when he’s pretending he isn’t.
“You’re doing that look,” Sukuna mutters.
“What look?”
“The one that says you’re thinking too much.”
“I’m thinking ‘mine,’” Satoru says, simple and bright, and Sukuna’s fingers pinch his side hard enough to make him yelp.
“Don’t get sentimental. You’ll scare the cat.”
“We don’t have a cat.”
“Good,” Sukuna says. “I don’t like competition.”
Satoru laughs, delighted, and squeezes his waist.
“Hungry? I made rice.”
“You burned rice.”
“I made replacement rice.” He nuzzles at Sukuna’s temple. “And if you’re good I’ll make that soup you like.”
“I’m always good.”
Satoru leans back enough to take him in, the set of his mouth when he’s trying not to smile, the way his chest moves under Satoru’s hands when he breathes, the exhaustion of an old war sitting lighter on him these days.
“You’re terrible,” Satoru says. “But you’re good to me.”
Sukuna looks away first.
He does that when the truth shows up too early in the evening.
“Your hand,” he says, flicking his gaze down. “You can leave it there.”
“Order received.” Satoru’s thumb strokes once along the edge of gauze. “Any soreness later?”
“I’ll live.”
“You always do.” Satoru kisses the corner of his mouth, quick, like punctuation. “C’mon. Rice. Soup. Then I’ll let you throw me at the couch during movie night.”
“You don’t let me do anything.”
“Semantics,” Satoru sings, slipping off the counter and catching Sukuna’s wrist as he goes.
He tugs, and Sukuna follows with a theatrical sigh, pausing only to snag the little pouch and flick the bathroom light off with his shoulder.
In the doorway, Satoru glances back and does the worst thing — he looks at Sukuna like the changing parts are a constellation he’s lucky to map.
“Hey,” he says, softer. “You okay?”
Sukuna rolls his eyes so huge it should crack the ceiling.
“I’m fine.”
“Because if you’re not, we can—”
“Gojo.” Sukuna steps into him, crowding him down the hall until Satoru’s back taps the doorframe.
Four hands would make this faster, two are enough.
He brackets Satoru’s face, thumbs pressing indents into his ridiculous cheeks.
“I am exactly what I say I am,” he says, even and sure, and the floor under them seems to agree. “And you’re insufferable.”
Satoru’s smile hits him like sunlight.
“Perfect.”
“Soup,” Sukuna orders, releasing him.
“On it, boss,” Satoru says, stealing one more kiss as payment and skipping backward toward the kitchen.
Sukuna watches him go for a heartbeat longer than he has to, then follows, still scowling, still pink at the tips of his ears, still himself.
The gauze sits warm under his palm for a second as he adjusts it.
He doesn’t need the sticker.
He doesn’t need the calendar.
He doesn’t need Satoru’s hand to stay on his hip all the way to the stove.
He lets all three happen anyway.
