ryomen sukuna hadn't made many mistakes in his long, bloodstained life. but youâyou were his greatest miscalculation. the way you laughed, breathless and bright, when he carried you through the palace gardens at dusk, your fingers tangled in the folds of his kimono like you weren't afraid to hold on. like he wouldnât ruin you. âslower,â you'd chide, cheeks flushed from the evening chill, and he'd scoff but slow his steps anyway, just to feel the warmth of your back pressed against his chest a little longer.
it was almost cruel, how easily you fit into the spaces between his ribs. the first time you coughed into your sleeveâa wet, ragged soundâhe'd pretended not to notice the flecks of red staining the fabric. but sukuna had survived centuries of war; he knew death when he smelled it. and now it lingered in the sweat-damp curve of your neck, in the way your hands trembled when you reached for him.
you never spoke of it. instead, you filled his silence with storiesâfoolish mortal things, about fireflies in summer and the way the river sounded when it froze over. once, half-asleep against his shoulder, you mumbled something about wanting to see the plum blossoms with him next spring. he didnât have the heart to tell you that by then, youâd be gone.
sometimes, in the dead of night, heâd press his palm to your chest just to feel the unsteady flutter beneath your skin. it was wrong, how small you felt under his hands. like he could crush you by accident. like he already was.
the first time you collapsed, it was in the middle of threading a needle. sukuna had been lounging across the room, pretending not to watch you squint at your embroideryâsome ridiculous pattern of cranes you insisted would bring him luck. then the needle clattered to the floor, and your knees buckled like cut strings. he caught you before you hit the tatami, your breath coming in shallow, awful gasps. âidiot,â he growled, but his voice cracked around the edges. he held you too tightly, fingers digging into your sides like he could keep you from unraveling if he just pressed hard enough.
you woke with his face hovering above yours, closer than you'd ever seen it. in the dim lamplight, the lines of his brow were softer, almost uncertain. âhavenât I told you not to scare me like that?â he muttered, but the hand cradling the back of your head was gentle. you tried to smile, but your lips felt stiff, like cracked parchment. âsorry,â you rasped, and his frown deepened. he lifted you effortlessly, carrying you to the low table where your abandoned embroidery layâthe craneâs wings half-finished, the needle still gleaming where it had fallen.
he didnât set you down. instead, he settled you against his chest, one arm wrapped around your waist while the other reached for the teapot warming over the brazier. âdrink,â he ordered, pressing the cup to your lips. the tea was bitter, laced with something earthyâmedicine, you realized, as warmth spread sluggishly through your limbs. âyouâre terrible at taking care of yourself,â he grumbled, but when you coughed, his fingers tightened around the cup. you wanted to tease him, to say something about the great king of curses playing nurse, but the words dissolved into another cough, wet and rattling.
later, when your breathing evened, he dragged his thumb over your bottom lip, wiping away a smudge of tea. you caught his wrist before he could pull away, pressing his palm flat against your cheek. his skin was rough with old scars, but his touch was careful, like he was handling something fragile. âkuna,â you started, but he cut you off with a sharp click of his tongue. âdonât,â he said, voice low. âdonât say it like that.â like a goodbye. you swallowed, watching the way his throat worked as he stared past you, at the unfinished embroidery. âthe cranes,â you murmured. âtheyâre supposed toââ âi know what theyâre for,â he interrupted. longevity. a wish for a thousand years. his jaw clenched.
there was something obscene about the way he loved you. it felt like a wound that wouldnât close, a fever that burned through his marrow long after the fire should have died. sukuna had spent lifetimes carving his name into history with violence, and yetâhere he was, undone by the press of your fingertips against his pulse. you were mortal. fragile. temporary. and still, when you sighed against his shoulder in sleep, something in his chest twisted so sharply he had to bite back a sound.
he hated it. hated the way your laughter made his ribs ache, hated how your scent lingered on his clothes long after youâd left the room. most of all, he hated the way your sickness made him helpless. for all his strength, all his curses, he couldnât tear this from you. couldnât rewrite the rot in your lungs with his own hands. the realization sat like a stone in his throat, heavy and suffocating.
sometimes, when you slept, heâd trace the shadows under your eyes with his thumb and imagine ripping the illness from your body, even if it meant swallowing it himself. but that was the cruelest joke of allâheâd survive it. you wouldnât. and so he stayed, pressing his lips to your clammy forehead while you trembled through another night, his arms a cage meant to keep you whole even as you splintered apart in them.
you asked him once, voice drowsy with exhaustion, why he stayed. âyouâre trouble,â heâd lied, flicking your nose. but the truth tasted like blood in his mouthâhe stayed because you were the first thing heâd ever had that was worth losing. and losing you would ruin him in ways no enemy ever could.
it was pathetic, really. the king of curses, reduced to counting your breaths like each one might be your last. heâd catch himself memorizing the slope of your shoulders, the way your fingers curled around his wrist when you dreamed, as if he could keep you with him through sheer force of will. but time slipped through his fingers like sand, and every morning, you woke a little paler, a little further away.
times where you'd chase him in the garden, panting with laughter, were long gone. now you could barely walk without sukuna's arm around your waist, your legs trembling like a newborn fawn's. he hated itâhated the way your knees buckled after three steps, hated how you'd bite your lip to keep from groaning when the pain flared up. but most of all, he hated the way you'd still smile up at him, like this was just another inconvenience and not the slow unraveling of your body. ârest,â he'd growl, lowering you onto the engawa when your breathing turned ragged. you'd protest weakly, âi wanna spend time with you,â and his chest would tighten like a vice.
each time someone dared ask him why he didnât just discard youâsome simpering courtier or wary servantâheâd crush their windpipe before they finished the sentence. their blood would splatter the shoji screens, their bodies tossed into the courtyard like discarded rags. no one questioned him after the third one. it was easier that way. less to clean up. less to explain to you when you woke from your feverish naps, blinking up at him with those tired, trusting eyes. âwhat happened?â you'd murmur, nodding at the fresh bloodstains on his sleeves. âhunting,â he'd lie, and you'd hum like you didnât know better, like he wasnât drowning in the weight of your faith.
he stopped leaving the palace altogether. the world outside could burn for all he cared. instead, he spent his days hauling you from one sunlit spot to another, chasing the weak warmth like it could stitch you back together. today, it was the engawa overlooking the koi pond, where you sat propped against his side, your fingers trailing absently over the embroidery in your lap. the cranes were nearly finished now, their wings arcing toward each other in an imperfect symmetry. âsee?â you said, voice thin but triumphant. âtold you iâd finish it.â sukuna stared at the way your knuckles whitened around the needle, the tremor in your wrist as you pulled the thread taut. âstupid,â he muttered, but his hand came up to cradle yours, steadying the shake. âshouldâve just let me buy you one.â you laughed, a sound like dry leaves. âwhereâs the fun in that?â
it happened on a morning so ordinary it felt like a betrayal. the air was thick with the scent of plum blossoms, their petals drifting lazily onto the engawa where sukuna had propped you against his side, your head lolling against his shoulder. you'd been quieter than usual, your fingers limp around the half-finished embroideryâone craneâs wing still missing its final stitches. âkuna,â you'd murmured, voice so faint he almost didnât catch it. when he turned his head, your eyes were already glazing over, your breath shallow as a wounded birdâs. he knew before your chest stilled. before the needle slipped from your fingers for the last time.
he didnât scream. didnât roar. sukuna simply pressed his lips to your temple and held you there, your body cooling in his arms as the plum blossoms kept falling, indifferent. it wasnât until the servants found him hours laterâyour corpse cradled against his chest, his fingers tangled in your hairâthat they realized he hadnât blinked. hadnât moved. âmy lord,â one dared whisper, and his head snapped up, eyes hollow. they fled before he could gut them.
sukuna couldn't physically cry, so the plum blossoms wept for him instead. petals fell like wet ink drops onto your still-warm cheeks as he pressed his forehead against yours, your lashes casting spiderweb shadows he'd never see flutter again. someone had left the shoji screens openâstupid, carelessâand the morning light painted stripes across your collarbones like prison bars. he wanted to hate it, the way the sun dared touch you now, when it had done nothing to keep you here. but his throat was too full of your name to speak.
âi've never been more sorry,â he rasped against your temple, his voice breaking in ways it never hadânot in battle, not in fury, not in the centuries of carnage that had shaped him. his lips moved against your skin like he was trying to press the words into you, to make them stick where breath no longer could. "i love you." the admission came out mangled, a confession wrung from the hollows of his ribs. he'd fought gods and men, but thisâthis stillness beneath his handsâwas the only thing that had ever brought him to his knees.
he didn't know how long he sat there, your weight limp in his arms, before his fingers found the half-finished embroidery still tangled in your lap. the crane's lone wing stared back at him, thread dangling like a snapped noose. sukuna didn't believe in prayers, but his thumb brushed over those clumsy stitches anyway, as if he could will them into flight. âstupid,â he choked out.
he didn't burn your fleshâwhich was one of the greatest mercies sukuna had ever allowed himself. instead, he dressed your body in layers of silk the color of dawn, fingers lingering over the embroidery at your collar where your cranes would never fly completed. he tucked the half-finished piece beneath your folded hands, thread still clinging to the needle like a final plea. when they lowered you into the earth, he didn't throw himself after you, though the weight in his chest begged him to. the hollow where you'd lived between his ribs ached like a missing limb.
days bled together without the rhythm of your breathing to mark them. servants stopped announcing themselves at his chambers, leaving trays of untouched food outside the shoji where your scent still clung to the tatami. sometimes he'd find himself turning to speak to you, the words dying on his tongue when his eyes caught the empty space where you used to curl against the low table, squinting at your needlework. the palace felt like a tomb, every corridor echoing with the ghost of your laughter, every garden path haunted by the memory of your fingers brushing petals he now crushed underfoot.
he would grow older, yet never wiserâjust angrier, at himself and the world for allowing such a thing to happen. sukuna had once laughed at the concept of graves, yet now he found himself kneeling before yours every morning, pressing his forehead to the cold stone marker as if it could bridge the impossible distance between flesh and memory.
