You gave him the chocolate as a joke.
“Just something sweet!” you said, smiling. “Try it after practice, okay?”
He beamed. “Thank you, YN! That was really thoughtful!”
He's curled up on your living room floor. Hoodie pulled over his head. Face red as a tomato. Knees to his chest. Breathing weirdly.
You peer over the couch. “Sho? Are you okay?”
“You’re literally sweating through your shirt.”
You walk over and kneel next to him. “Did you overwork yourself again? You always go too hard—”
“I didn’t do anything!” he blurts, then clamps his hand over his mouth.
“…Wait. Sorry. I didn’t mean to yell.”
“…Shoyo. What’s going on?”
He lets out a groan and flops onto his back, hoodie covering his entire face now. “I can’t tell you. It’s—embarrassing.”
You pull the hoodie up just a little. His eyes are wide. Glazed. Face crimson.
“Did something happen after you ate the chocolate?”
He blinks. Then sits bolt upright.
“WHAT WAS IN THAT CHOCOLATE, Y/N?!”
“Y-Yeah you gave it to me!!”
“I didn’t think you’d eat the whole thing!! It was labeled like... love booster or something weird—”
“WHY WOULD YOU GIVE ME A LOVE BOOSTER?!”
You’re both screaming now.
He immediately covers his mouth again. “I’m sorry I didn’t mean to yell again.”
“…S-So you’re feeling… stuff?”
He stares at the ceiling.
His ears turn red.
“…My heart’s been racing for an hour, I tried doing sit-ups to calm down, but then I started thinking about you and it made it worse, and then I looked at your hoodie on the couch and I just—”
“Wait, you thought about me—”
“CAN I SLEEP IN THE BATHTUB?”
“I just need to cool down. Please. Just. Don’t look at me for like five hours.”
He scrambles up, dragging your throw pillow with him, practically sprinting to the bathroom.
You’re left in the living room, blinking.
You didn’t even know someone could get horny and shy at the same time.
You handed it to him before training. Just a little wrapped-up chocolate bar.
“For good luck,” you said with a smile.
He took it with that awkward nod of his.
“…Thanks.”
He didn’t think anything of it.
Until 40 minutes into practice—he messes up a serve.
Atsumu smirks. “Yo, Tobio. You okay?”
Kageyama scowls. “I’m fine.”
But he isn’t.
Because his body feels… off.
Warm. Hyperaware.
Like every inch of his skin is tuned to high sensitivity.
And his thoughts? Not focused on volleyball.
Later, he finds you alone near the back hall, refilling your water bottle.
His footsteps echo as he walks up, and you turn.
“Hey—oh. Tobio. What’s up?”
He stops a few feet from you. Frozen.
You tilt your head. “Everything okay?”
Just stares.
Hard.
Eyes dark. Tense. Flicking from your face… to your mouth… to your neck… back up again.
“…Why are you looking at me like that?”
“…You sure? You’re kinda—sweating. A lot.”
He jerks his eyes away. “…It’s hot.”
You frown. “You’ve been acting weird since earlier.”
Then quietly—his voice low:
“…That chocolate you gave me.”
You straighten. “Wait. Did you eat all of it??”
His jaw clenches. “You told me to.”
“Oh my god—Tobio, I didn’t think you'd—”
You cut yourself off.
He’s still staring at you. His eyes are scanning you like he’s trying to figure something out.
“…I’m distracted.”
You freeze.
“I can’t stop thinking about—”
He cuts himself off.
His fists are clenched. His ears are red.
“…I keep messing up in practice,” he says, voice tight. “Because I keep thinking about you. And that chocolate. And the fact that I don’t know if this is your fault or mine.”
He stares back, like he’s one breath away from either kissing you or short-circuiting.
“…Is it bad?” you whisper.
He swallows hard.
Then—leans closer.
“I don’t know yet.”
His eyes are burning. “I might need another piece to find out.”
You gave him the chocolate half as a joke, half as a “you need sugar because you’re a grump” gift.
He rolled his eyes.
“Are you bribing me now?”
You grinned. “Maybe.”
He took it with that classic bored Tsukki expression.
Tore off the wrapper. Ate it. Didn’t even blink.
“Thanks,” he said flatly. “Wasn’t bad.”
He’s shirtless in your apartment kitchen.
Standing near the fridge. Glass of water in one hand.
The other shoved into his pocket like he’s trying to physically hold himself together.
“…This is annoying,” he mutters.
You blink at him. “What is?”
He exhales sharply. Pushes his glasses up the bridge of his nose. His cheeks are pink. His voice is strained.
“My skin feels hot. My brain is loud. And for some reason, I can’t stop looking at you.”
“Tsukishima, did you—wait—did you eat all the chocolate?!”
He glares. “Why the hell did it taste like cinnamon and lust.”
He steps forward.
Not fast. But on purpose.
“You thought you could mess with me, huh?”
His voice is low now. Dangerous. Curious.
You laugh nervously. “W-wait, it was just a joke gift—Tsukki—”
He cuts you off with intense eye contact.
Head tilts slightly.
Then—he smirks.
The rare kind. The one that sends shivers down your spine.
“…Why don’t we see if it worked?”
And then he leans in.
REAL close. His breath brushing your jaw. His mouth just a hair from your ear.
“…Don’t worry. I’ll grade your performance later.”
When you gave him the chocolate earlier, it was just playful.
“It’s fancy,” you said. “Imported. Thought you’d like it.”
He raised an eyebrow, unwrapped it with one hand, and popped a piece into his mouth.
Then he licked his thumb slowly—eyes locked on you.
“…Damn, YN. Trying to seduce me?”
You blinked. “What?! No! It’s literally just chocolate.”
He chuckled. That low, rich, sin-in-a-suit kind of laugh.
“Well,” he said, licking his lip. “Too late.”
Fast forward to later that night.
You come home exhausted.
Your bag hits the couch. Your hair’s a mess. You're ready to collapse.
You call out: “Tetsu? I’m home!”
You find him in the bedroom, hoodie on, hood up, sleeves rolled up, head tilted back against the headboard.
He’s breathing hard. Eyes half-lidded. Hair damp at the nape of his neck.
“…Tetsu?” you whisper, walking closer.
He opens his eyes. Panic. Tries to sit up.
“Don’t—don’t come close.”
You frown. “Are you okay?!”
“I’m fine,” he rasps. “Just. Uh. Tired.”
You blink. “You’re flushed. And sweating. Did you eat something weird? Are you—”
He won’t meet your eyes.
He knows what he did.
But he doesn’t want to bother you. You’re tired. He told himself he could wait it out.
You sit beside him on the bed and slowly rest your hand on his thigh.
“…Tetsu, baby. Are you okay?”
Eyes wide. Whole body flinching. Knees jerking together like a cartoon character.
“Please. Don’t touch me right now. If you do, I’m going to make the worst decision of my life.”
He exhales shakily. Hoodie hood still over his head like he’s hiding from God.
“…Like asking you to ruin me right now when you literally just got home from work.”
Your mouth opens. Then closes.
“…So you did like the chocolate.”
“Woman. You spiked it with sex. Of course I did.”
You sent him the chocolate during his stream. Just a casual “I saw this and thought of you” moment.
He reads your message aloud between matches.
Chat spams:
“OOOHHH 😏”
“KENMA CONFIRMED WHIPPED”
“WE SHIP”
“HE SAID LOVE U???”
He doesn’t react. Just munches on the chocolate quietly.
For a while.
He gets quiet. Like, even more than usual.
His hoodie is pulled up. He's slouching harder.
He keeps tugging his hoodie strings. Pulling the fabric up over his mouth. Flushed cheeks. Hair sticking to his forehead.
The camera catches him swallowing hard. Fidgeting.
No warning. No “brb.” Just poof.
Your phone vibrates 30 seconds later.
🐱 Kenma: “my whole body is buzzing. why?”
You: “What? Did something happen?”
🐱 Kenma: “…wait.”
🐱 Kenma: “aphrodisiac??”
🐱 Kenma: “YN.”
🐱 Kenma: “is this your way of saying you want me?”
You’re typing a reply when—
Ping.
Kenma. Shirtless. Lying back on his bed. Hair tousled, cheeks red, lips parted.
Hoodie still half-on. Collarbones visible.
“Fix this.” written across his palm in messy Sharpie.
🐱 “i’m not mad. just desperate.”
🐱 “so. what’s your plan?”
🐱 “irl DLC? or do i keep suffering on main.”
Earlier that day, he beamed when you handed him the chocolate.
“CHOCOLATE?! FROM YOU?! THANKS, Y/N!!!”
He ate it with zero hesitation. Even licked the wrapper.
You: “Don’t eat the foil—”
Fast forward three hours.
He’s fresh out of practice, hair damp from a shower, towel around his neck, face flushed — not from training. He’s lying on the couch in gray sweatpants, breathing uneven, staring at the ceiling like it personally offended him.
“Why do I feel like I ran a marathon after training…?”
His body’s hot. His thighs are tense. His fingers are twitching.
He scrolls through his phone.
Missed call from Y/N.
He sits up instantly. Then groans.
The ache between his legs is painfully obvious now.
You knock on his apartment door, holding some takeout.
“Bo? You okay? You sounded kinda off earlier.”
The moment he opens the door, you're hit with warmth — like the air shifted.
He looks… messed up. Sweaty. Hair sticking to his forehead. Face flushed. Pupils blown.
“Y/N…” he breathes out. “Hey…”
You frown. “Did you get sick or something?”
He backs up a little, clearly trying to keep his distance — but his sweatpants are doing zero hiding.
“I… don’t know. I feel weird. Like… warm? All over?”
You squint at him, and it clicks.
“…You ate the chocolate, didn’t you?”
“Yeah?? It was good!! Wait—why are you looking at me like that?”
Then he pauses. Blinks.
Eyes widen. His voice cracks.
“Y/N… did you make me horny chocolate?!”
Your silence is the answer.
He stumbles back and grabs the couch for support. “I THOUGHT I WAS DYING.”
You set the takeout down. “You're not dying, Bo. You're just–”
“I’M HARD FOR NO REASON.”
Bo starts panicking. “DOES THIS MEAN YOU WANNA–? LIKE–DO THINGS?! IS THIS YOU SAYING YOU LOVE ME?!”
You step closer.
His eyes go huge.
You whisper: “If I said yes, would you calm down?”
“NO,” he yells, immediately wrapping his arms around you like a koala. “I’D GET WORSE.”
You gave him the chocolate earlier that day, wrapped neatly with a ribbon.
He accepted it with that gentle smile of his.
“Thank you, YN. That’s very sweet of you.”
He popped one into his mouth like it was nothing.
1 hour later.
Your phone buzzes.
I feel strange.
Warm.
Slightly flushed.
Was there… something in that chocolate?
We should talk. In private.
You show up to his apartment expecting maybe a flustered mess.
He answers the door in a black turtleneck and slacks, glasses on, hair slightly tousled like he’d run his hands through it too many times.
He smiles, but it doesn’t reach his eyes.
“That’s the problem, isn’t it?” he murmurs, letting you in.
You sit across from him. He pours tea. His hands are steady. Too steady.
But his ears are red.
“…I didn’t want to accuse you,” he says, tone smooth but eyes sharp, “but knowing you and your antics…”
He leans forward, just slightly. The look he gives you?
Illegal.
“Be honest. You knew what that chocolate would do to me, didn’t you?”
You: “...Not really. I mean—”
“Because ever since I ate it, I’ve been thinking about you. In ways I shouldn’t during meetings. My body’s tense. My mind’s loud. And I can’t focus. At all.”
He says it like he’s scolding you — but his gaze drifts. Down your lips. Your neck.
“You owe me an apology,” he adds, voice a shade lower.
“…Or maybe something better.”
Kita came in from the fields like he always does—shirt a little damp, hands calloused, face glowing with fresh air and quiet discipline. You handed him his usual lunch, neatly packed like always, but this time...
You added a small chocolate dessert.
"Thought you deserved a treat," you say sweetly.
He blinked at you, then gave a soft smile.
“Thank you. I appreciate it.”
He eats it without a second thought. It melts on his tongue.
You find him standing by the kitchen sink, staring out the window. Silent. Tense. His hand is resting low on the counter like he's grounding himself.
You wrap your arms around his waist from behind.
“…Something’s off,” he murmurs. “Feels like I drank too much sake. Body’s hot. But I haven’t had a drop.”
He swallows. “Can’t think straight. My hands are… restless.”
You kiss the back of his neck. He stiffens.
"Y/N…” His voice cracks just slightly.
You move to stand in front of him. He can’t meet your gaze. He’s flushed. Stiff in more ways than one.
You gently cup his face, thumbs brushing his cheeks.
“Shin,” you whisper, leaning up to kiss the corner of his mouth. “You never ask for help… but I can feel what you need.”
He lets out a breath he didn’t realize he was holding, eyes finally locking with yours.
“You’re doin’ dangerous things, sugar,” he says softly. His hands hover at your hips, trembling. “I’m tryin’ to be good.”
You smile, kiss him again, this time a little deeper. “You’ve been too good.”
And his restraint shatters, just a little.
His lips find your neck.
His fingers tighten at your waist.
And all that farm-boy discipline?
Gone.
You gave him one. Single. Piece.
A sleek little chocolate truffle wrapped in gold foil.
“Ohhh fancy chocolate from YN~? Don’t mind if I do,” Atsumu cooed, grinning as he popped it into his mouth.
“Sweet just like ya,” he added with a wink.
You rolled your eyes. “Shut up and eat it.”
He did. Smug. Smirking. Clueless.
Your phone starts buzzing.
🐯 atsumu.miya: “YN”
🐯 atsumu.miya: “I can’t stop thinkin’ about ya.”
🐯 atsumu.miya: “Like. Physically. CAN’T.”
🐯 atsumu.miya: “Was that chocolate spiked or are you just naturally evil???”
You laugh—until you hear your doorbell.
You open it to find Atsumu, hoodie sliding off one shoulder, his hair a total mess, face way too flushed for someone who just "happened to be in the area."
"You did somethin’ to me,” he says accusingly, stepping inside like he owns the place. “That chocolate messed me up.”
He slumps on your couch dramatically, pouting. His legs are spread. His hoodie’s halfway zipped. He looks like a chaotic thirst trap.
“I'm so warm. And twitchy. And HARD. And—don’t look at me like that!”
You smirk, sitting beside him. “I didn’t tell you to eat it all.”
He huffs. “Ya knew I would.”
Then he leans in—eyes dark, voice low.
“You did this to me, YN…”
A little whine slips out as his fingers wrap around your wrist.
“Might as well finish what ya started, right?”
You hand him the chocolate after practice.
He eyes it suspiciously. Sniffs it.
“What’s in this?” he asks, like you're offering poison.
“Just chocolate,” you say sweetly. You don’t flinch. That should’ve been his first warning.
He regrets it immediately.
Your phone rings.
Caller ID: Kiyoomi 🍃
“Y/N,” he says tightly. “I don’t feel right.”
You’re grinning already. “Why? What’s wrong?”
“My skin’s hot. My head’s fuzzy. My pants are… tight.”
There’s a pause. You can feel his glare through the phone.
“You better pray this wears off. If not… we’re going to have a long night.”
There’s a knock at your door.
You open it—and there he is.
Black hoodie. Mask on. Gloves still on his hands like he’s clinging to the last shred of control.
But his hoodie’s halfway unzipped, exposing just enough of his collarbones to make your brain stop functioning.
“What are you wearing?” you ask, a little too amused.
You smile sweetly. “Kiyoomi… are you flustered?”
He storms past you. “I’m boiling. And you’re making it worse.”
You follow, barely hiding your giggle. “You didn’t have to come over, you know.”
“I didn’t have a choice,” he mutters, yanking off his gloves. “My body feels like it’s craving you. You did something to me. Admit it.”
You lean close, fingers brushing his collarbone, watching him twitch under your touch.
“So what if I did?”
He exhales hard, barely keeping his hands off you.
“You’re evil,” he mutters.
Then adds, voice dropping lower—
“…but I like it.”
