the day Sukuna realized he needs to marry you.

Ryomen Sukuna was having the kind of day that made him want to commit a felony.
Work had been an absolute, unmitigated disaster. His clients were being brain-dead idiots, his emails had been piling up since 6:00 AM, and his boss had the audacity to drop a massive, last-minute project on his desk right as he was packing up to leave. By the time he finally unlocked the front door to your shared apartment, his jaw was clenched so tight his teeth ached. He was exhausted, he was pissed off, and he was fully prepared to pour himself a massive glass of whiskey and not speak to a single soul for the rest of the night.
He pushed the door open, dropping his keys into the bowl by the entrance with a loud, aggressive clatter. He shrugged off his suit jacket, loosening his tie with a harsh yank.
“I’m home,” he called out, his voice a low, gravelly grumble.
He expected you to be in the kitchen, or maybe curled up on the couch watching some trashy reality TV show. He expected you to ask him how his day was, which would inevitably lead to him ranting for twenty minutes straight.
Instead, there was silence.
Sukuna frowned, his bad mood spiking just a fraction. He walked down the hallway and stepped into the living room.
He stopped dead in his tracks.
You were sitting cross-legged on the floor, hunched over the coffee table. The entire surface was completely covered in hundreds of microscopic, brightly colored plastic bricks. You were wearing one of his oversized t-shirts, your hair tied up in a messy bun that was slowly falling apart.
But the best part? The absolute most ridiculous, endearing part?
You were squinting so hard your nose was scrunched up, and the very tip of your tongue was poking out of the corner of your mouth in pure, unadulterated concentration. Your fingers, which were currently trying to snap a tiny, translucent green piece onto a microscopic brown cylinder, were trembling slightly from the effort.
You hadn’t even heard him come in. You were entirely, completely consumed by your task.
Sukuna stood there in the doorway, his suit jacket dangling from his fingers. He didn’t say a word. He just watched you.
You were a serial hobbyist. Every month, it was something new. Knitting, painting by numbers, making weird little clay frogs that currently haunted his nightstand. He usually just rolled his eyes, funded your little hyper-fixations, and let you do your thing.
But this? This tiny, intricate Lego flower shop you had apparently bought today? It had you in a chokehold.
Snap.
The tiny green piece finally clicked into place.
You let out a massive, dramatic gasp of victory, throwing your hands up in the air like you had just won the Super Bowl. “Yes! Take that, you stupid little plastic bitch!”
Sukuna let out a sudden, loud snort.
You jumped, spinning around so fast you nearly knocked over a pile of pink bricks. When you saw him standing there, your eyes lit up like a Christmas tree. The sheer, radiant joy on your face was blinding.
“Babe!” you squealed, scrambling up onto your knees. You carefully scooped up the tiny, completed structure in your hands and held it out toward him like it was the Holy Grail. “Baby, look! Look what I did!”
Sukuna slowly walked over, dropping his jacket onto the sofa. He looked down at your hands.
It was a tiny, incredibly detailed Lego flower shop. And sitting right in front of it was a single, slightly lopsided plastic rose that you had clearly customized.
“I made you this one,” you beamed, your chest puffing out with pride. You were practically vibrating with excitement. “It’s for your desk at work! Because you said your office is depressing! Do you like it?!”
Sukuna stared at the tiny plastic flower. Then, he looked at you.
You had a faint smudge of left over dinner on your cheek. Your oversized shirt was slipping off one shoulder. You were looking up at him with such pure, unfiltered adoration and excitement over a piece of plastic that it actually knocked the breath out of his lungs.
And just like that, it happened.
The stress of the last fourteen hours? Gone. The anger at his clients? Evaporated. The tension in his shoulders, the pounding headache behind his eyes, the overwhelming urge to burn his office building to the ground? It all just melted away, completely washed out by the sheer force of your ridiculous, beaming smile.
He didn’t just love you. That wasn’t a strong enough word anymore.
He looked at you, sitting on the floor surrounded by plastic bricks, offering him a fake flower to make his bad day better, and a single, crystal-clear thought rang through his head like a bell.
I need to marry this girl.
Not ‘I want to.’ Not ‘someday.’ Need. He needed to marry your crazy ass. He needed to lock this down permanently, because if he had to go through the rest of his miserable, stressful life without coming home to you poking your tongue out over a Lego set, he was going to lose his fucking mind.
“Sukuna?” you blinked, your smile faltering just a little when he didn’t immediately respond. You lowered your hands slightly. “Do you… not like it? I know it’s kind of dumb, but—”
“Shut up,” he breathed, his voice thick.
Before you could even process the command, he dropped to his knees right in front of you, completely ignoring the fact that he was crushing at least ten Lego pieces under his expensive suit pants.
He reached out, his large hands gently cupping your face. He didn’t even look at the flower shop. His red eyes were locked entirely on yours, burning with an intensity that made your heart stutter in your chest.
“Babe?” you whispered, suddenly hyper-aware of how close he was. “Are you okay? Was work bad?”
“Work was a fucking nightmare,” he murmured, his thumbs brushing over your cheekbones. “But I don’t care anymore.”
“You don’t?”
“No.” He leaned in, pressing his forehead against yours. He let out a long, shaky exhale, the last of his stress leaving his body. “I love it, baby. It’s perfect. I’m putting it right in the middle of my desk.”
Your smile instantly returned, brighter than before. “Really?!”
“Really,” he chuckled, the sound deep and vibrating against your skin. He tilted your chin up, capturing your lips in a slow, desperate kiss. It wasn’t heated or rough; it was incredibly soft, filled with a kind of overwhelming reverence that made your toes curl.
When he finally pulled back, he kept his face inches from yours. He looked down at your lips, then back up to your eyes.
“I’m gonna marry you,” he said.
It wasn’t a proposal. It wasn’t a question. It was a statement of absolute, undeniable fact. He said it casually, like he was commenting on the weather, but the weight behind his words was heavy enough to anchor a ship.
Your brain short-circuited. You sat there, frozen, the tiny Lego flower shop still clutched in your hands. “What?”
“You heard me,” he smirked, his usual arrogant confidence bleeding back into his tone. He leaned in and pressed a loud, wet kiss to your cheek, then your jaw, then the sensitive skin just below your ear. “I’m gonna marry your crazy ass. Put a ring on your finger so big you won’t be able to lift your hand to build these stupid little toys.”
“They’re not stupid!” you squawked, your face flushing bright red as his words finally registered. “And you can’t just drop that on me while I’m holding a Lego!”
“I just did,” he laughed, wrapping his arms around your waist and pulling you flush against his chest, completely ruining your posture. He buried his face in your neck.
You let out a breathless, watery laugh, carefully setting the flower shop down on the table before wrapping your arms around his broad shoulders. You ran your fingers through his pink hair, feeling the last of the tension bleed out of his muscles.
“Okay,” you whispered, pressing a kiss to the top of his head. “Okay, Ryomen.”
“Good,” he mumbled against your skin. He shifted slightly, his knee crunching against a pile of plastic. He winced. “Now, help me up. I think a fucking Lego is embedded in my kneecap.”
“I told you to take your work pants off first!”
“Just kiss me again and shut up.”
