Relationship Headcanons for the V3 Boys!
So this is my first post! I’m writing headcanons for pre and post confession for all the V3 boys except Korekiyo and Ryoma. (Sorry to their fans😓) You can still request something about them though!
With that out of the way please enjoy!
.ᐟ.ᐟ💚 Rantaro Amami 💚.ᐟ.ᐟ
Rantaro is the type of guy who would subtlety observe you from afar. He watches and picks up on your likes and dislikes without you ever knowing. Rantaro knows your favorite snack, drink, and any other things you may enjoy.
It’s almost uncanny how often he shows up wherever you are. The library? He’s already there. The kitchen? Just passing through. He says it’s coincidence, but let’s be honest, he totally planned it.
Rantaro’s flirty, but in that effortlessly smooth way that always makes you wonder if he’s being serious. “You know, I think your smile might be the reason I keep coming back here.” And then he just walks away like it was nothing.
I can see Rantaro being protective over you, but in a quiet way. At least before you two are official. If someone upsets you, he doesn’t confront them directly unless necessary. Instead, he’ll pull you aside, distract you, offer a snack, or say something calming like, “Don’t let them ruin your day. You deserve better than that.”
Rantaro would struggle with confessing.
Rantaro’s biggest fear is dragging you into anything dangerous or complicated, especially considering his unknown past. He’ll keep his feelings buried deep, unless he thinks you’re slipping away from him. In which case he would panic immediately but still somehow manage to look calm on the outside even though he is malfunctioning on the inside.
Would totally act normal until you are gone.
Around you, he’s composed and chill. But the second you leave? He sighs, runs a hand through his hair, and mumbles about how he’s got it bad.
Once you’re together, the teasing tones become laced with more warmth. He still flirts, but there’s sincerity in his compliments now. “You’re incredible. I hope you know that.”
He’s not clingy, but he loves physical affection in quiet moments. A hand on your shoulder, brushing his fingers against yours while walking, gently pulling you into his side when no one’s looking.
He’ll never cause a scene… but if someone flirts with you, he’ll just raise a brow and wrap an arm loosely around you while talking about “his partner” in casual conversation.
Rantaro trusts you completely and doesn’t try to control you. But he will quietly ensure you’re safe, especially in any dangerous or tense situations. You’ll rarely notice it, but he’s always watching your back.
You’d never expect it, but his drawer has little things you’ve given him or that remind him of you, ticket stubs, your handwriting on a napkin, a photo. He looks at them when he’s alone.
When you fall asleep in his arms, he’ll gently stroke your hair and murmur things like, “Thank you for choosing me… I hope I never lose you.”
‧₊˚✩ 🪐✩˚₊‧ Kaito Momota ‧₊˚✩ 🪐✩˚₊‧
Kaito wouldn't exactly be subtle about his crush on you. He flirts often, with cheesy lines like: “Hey, did it hurt? When you fell from the stars, cause you’re clearly from another galaxy!” But the second you tease him back? He stutters and turns beet red.
Everyone knows he likes you. Everyone. The way he lights up when you enter the room, how he randomly yells your name across the hallway just to wave, it’s endearing, but can be little embarrassing sometimes.
Kaito tries to ask for “advice” about you from Shuichi or Maki and ends up accidentally making it sound like he’s already dating you. Shuichi’s like: “Wait, you’re not?” and Kaito’s like, “N-NO!! I mean... not yet!”
Kaito would be protective 100%
If you so much as trip, he’s at your side like “ARE YOU OKAY?! WHO PUT THAT ROCK THERE?! I’LL PUNCH IT INTO SPACE.” He’s always ready to stand between you and any danger, even imaginary.
Kaito seems like the type of dude who would practice his confession in the mirror.
“Hey! I like you! No, no… That sounds too normal. Uh… You’re like a star… No, wait, cheesy!” He ends up nervously blurting it out way before he plans to, probably during a moment of emotional tension.
He acts confident about liking you, puffing out his chest, throwing an arm over your shoulder. But the second you get close or compliment him? He malfunctions like a certain robot with a short circuit.
Kaito would be the loudest boyfriend EVER.
“Hey everyone! Did you know [Name] is my partner?! The best person in the UNIVERSE! That’s right, they said yes!” Kaito wants the whole world to know. He’ll shout it from the rooftops, and probably has.
He greets you with hugs so big and enthusiastic, you often lose your balance. If you’re smaller than him? Prepare to be lifted and spun like you’re in a rom-com.
He constantly hypes you up. “You’re amazing!” “You’re gonna crush that test!” “You got this, I believe in you!” His faith in you is unshakable, even when you doubt yourself.
I feel like Kaito would get jealous really easily and just become really inconsiderate.
If someone flirts with you, he tries to play it cool. He doesn’t. He loudly interrupts the conversation like: “So anyway, babe, wanna go look at the stars alone together? Right now?”
Look he's handling it the best he can!
When you’re vulnerable or sad, he drops the loud act. He gets gentle. He listens. Rubs circles on your back. “I’m here, okay? I’m not going anywhere.”
He tries to act like romance isn’t a big deal but he’s the kind of guy who would build a homemade planetarium out of LED lights just so you can stargaze indoors.
When Kaito shares his hopes and dreams with you they will always include you in some way.
“When I go to space someday… I want you to be there. Not just for the launch, but… y’know, in my life. Always.” He’s already imagining your future together, one where you’re both reaching for the stars.
He clings like a koala when you sleep together. Arms wrapped tight, head buried in your neck. He’s warm, both literally and emotionally, and hates letting go.
Gonta wears his heart on his sleeve. He’s so kind and attentive to you that everyone else instantly knows he has a crush. He just thinks he’s “being a gentleman.”
Gonta offers to carry your things, fix broken objects, protect you from bugs (unless you like them, in which case he brings you bugs as gifts), and walk you back safely every time. "Gonta not want you to get hurt!"
Gonta is terrified of making you uncomfortable.
Gonta second guesses himself constantly. He’ll start to say something sweet and then panic: “Ah! Is Gonta being weird again? Gonta sorry!!”
The smallest compliment from you turns him into a blushing mess. “Y-You think Gonta’s strong? Gonta… Gonta very happy…”
He tells his insect friends about you like they’re his advisors. “Do you think [Name] would like Gonta’s new tie? No? Maybe Gonta wear different one…”
Gonta would want to confess, but he feels he isn't 'good enough.'
He holds back out of fear you’d never like someone like him. “Gonta is gentleman, but Gonta not smart like others… maybe [Name] deserves better.”
He constantly puts your safety first. Not in a controlling way, but a sweet, instinctive one. Crossing the street? He’s shielding you with his whole body. Loud noise? You’re behind him. You sneeze? He panics and wraps you in a blanket.
He holds open doors, pulls out chairs, walks on the outside of the sidewalk, even when you tell him he doesn’t have to. “Gonta want to be best boyfriend ever!”
Gonta’s hugs are massive. You completely disappear in his arms, and he’s so warm. He’s always afraid of hurting you, though, so he asks “Is this too tight?” every five seconds.
Gonta is unbelievably loyal.
Gonta never even looks at anyone else. “Gonta only want to be with you. You make Gonta heart feel happy.” If someone flirts with him, he doesn't even notice unless you point it out, and then he apologizes to you for it.
He crafts you things from leaves, flowers, or pretty stones. Occasionally, he gives you insects (especially butterflies or beetles) as tokens of affection. “This one is very rare! Only for you!”
He struggles with poetic or romantic speech but says the most heartwarming things in his own way. “Gonta doesn’t know how to say it fancy… but Gonta loves you. More than anything.”
He gently encourages you to learn about insects. If you're afraid of them, he’s totally understanding, but if you're willing to try holding one, he lights up like a Christmas tree.
He cried when you said 'I love you.'
He was so overwhelmed with happiness and disbelief, he teared up. “R-Really? You love Gonta? Gonta… Gonta never been so happy…”
₊˚✧ ﾟ. Shuichi Saihara₊˚✧ ﾟ.
Shuichi tries so hard to keep it cool, but internally he’s melting every time you so much as look at him. One compliment? Red-faced. One smile? Heart racing. You touch his shoulder? He might need CPR.
He’s constantly sneaking glances at you when he thinks you won’t notice. If you do catch him, he’ll pretend he was looking at something else and nearly trip trying to get away.
He lingers near you whenever possible, quietly standing nearby or walking next to you. He listens intently to everything you say but rarely chimes in unless prompted, he’s afraid of saying something dumb.
Shuichi low-key has stalker vibes.
Not in a creepy way—but he remembers everything. Your favorite color, the things you collect, even small details you said once and forgot about. He uses that info to do sweet things from the background, like leaving you snacks you like or lending you a book you mentioned in passing.
Shuichi analyzes every interaction with you like it’s a full-blown case. “Did they laugh at my joke because it was funny or because they were being polite?” He rewatches conversations in his head at night, second-guessing every word he said.
He doesn’t confess for a long time because he’s terrified of losing you—even just as a friend. “I… I’d rather stay close and pretend I don’t feel this way than risk ruining everything.”
Even after getting together, he’s awkward, blushing easily, fumbling over compliments, but he’s happy. He has this soft smile that only appears when you’re around. You’re his safe place now.
Shuichi is all about soft touches: brushing your hand, leaning his head against your shoulder, or gently playing with your fingers. When you kiss him first? He freezes for a second, then melts.
He doesn’t yell or act brash, but if someone hurts or upsets you? Shuichi goes full detective mode to expose the truth and make sure you’re okay. He’ll gather evidence, not punches.
You could talk for hours and he’d never interrupt. He makes you feel heard in a way that’s so rare, validating your feelings, remembering everything you say, and offering calm, reassuring advice.
You’re the only person he’ll open up to when he’s struggling. “I’m… not okay today. But I’m trying. Can I just stay near you for a while?”
Shuichi is the type to get silent when jealous.
He trusts you, but if someone’s being too friendly, his expression goes just a bit flatter, quieter. He doesn’t confront them, he just stays closer to you than usual, gently gripping your sleeve or hand.
He won’t admit it, but he fantasizes about little domestic things like making you coffee, reading together on rainy days, or walking home hand-in-hand after shopping. Your first “I love you” made him cry (he swears he had something in his eye).
“You remind me that I’m more than what I fear… More than what I doubt. Being with you makes me want to be braver.” He says that with watery eyes, forehead resting on yours.
Keebo isn’t sure if what he’s feeling counts. He spends hours questioning whether a robot can fall in love, then immediately blushes (yes, somehow) when you so much as wave at him. “Th-this must be... a data processing issue!!”
He tries way too hard to sound intelligent and composed in front of you. “Greetings! I have statistically determined that you are… aesthetically optimal—I mean, good! You look good!”
Keebo downloads every available article about romance, dating, and human emotion. He cross references romantic tropes, analyzes your personality type, and still has no idea what he’s doing.
Accidentally overheats when around you.
When you touch him, compliment him, or get too close, he starts sparking slightly. “Ah! Please don’t worry—my cooling system is simply malfunctioning due to… environmental affection stimuli!!”
He worries he can’t be a good partner because he isn’t human. He talks to Miu (regrettably) and even Gonta about how to be 'more relatable' so you might like him.
Eventually Confesses Out of Overload.
After weeks of internal turmoil, he blurts it out in a totally unexpected moment. “I have concluded that I am in love with you!! I apologize for this inconvenient emotional outburst!!”
He reads books on relationships daily. “According to this article, I should now hold your hand. May I?” He wants to get everything “right” and worries he’ll mess up, even though you reassure him constantly.
Once he accepts that he can love, he leans hard into it. Flowers, handwritten notes (printed in neat typeface), random monologues about how much he cherishes you. It's adorable.
Doesn’t Understand Jealousy at First.
“I do not possess envy protocols.” But then someone flirts with you and he’s immediately like: “Excuse me. They are taken. Please recalibrate your behavior.”
You’re the person he trusts most when it comes to understanding the human experience. He asks deep questions: “What does missing someone feel like?” “Why do humans cry when they’re happy?” You help him feel more real.
He’s hyper-aware of his strength and mechanical nature. He always checks: “Am I holding your hand too tightly? Is this comfortable for you?” His protectiveness comes from care, not fear.
Keebo loves being called your boyfriend.
It short-circuits him every time. “Y-you called me your partner again… Please repeat it. For data collection.”
Acts like you’re the best thing to ever happen to him (because you are)
“I never thought a machine like me could feel this. But now I know… I was programmed to love you.”
(˚ ˃̣̣̥⌓˂̣̣̥ )Kokichi Oma(˶˃ ᵕ ˂˶)
Kokichi is constantly flirting with you, but it’s always wrapped in sarcasm or jokes. “Hey, wanna skip class and get married? I mean, unless you’re too chicken~”
Annoying on purpose just to get your attention.
He pokes your cheeks, steals your pen, sits in your chair, calls you dumb nicknames like “Lovebug” or “Dumb-dumb.” You tell him to stop? He does it more. But the second you seem actually upset? He backs off immediately, eyes flicking to the floor.
If you hang out with someone else too much, he’ll act all fake-casual about it. “Ooooh~ Is [Name] cheating on me already? I’m devastated!” But when he’s alone? He sulks. Quietly. Like a kicked puppy.
Someone talks badly about you? Kokichi is already halfway through planning their social downfall. But if you confront him about it he's all like, “What? Me? Threaten someone? Pft. I’m too cute and innocent for that. 😇”
Pushes you away when he gets too nervous.
He gets scared of being real around you, so when the emotions start to feel too genuine, he says something cruel like, “As if someone like you would ever love a liar like me.” Then leaves before you can respond.
The confession is a mess.
It’s probably an emotional breakdown disguised as a joke. “Okay, haha, surprise—I like you. There, I said it. Now laugh or run away or scream or something, I don’t care.” (He 100% cares.)
Kokichi becomes even more annoying. But now he holds your hand while doing it. “If I’m gonna be unbearable, I might as well do it while cuddling~!”
Blushes when you’re affectionate.
You say “I love you”? He grins smugly. “Obviously, who wouldn’t?” But then you kiss his cheek and he short-circuits. “W-Wait, hold on, you can’t just DO THAT!!”
If Kokichi lets you see him without the lies, even just for a moment, it means he trusts you more than anyone else. He’ll sit quietly next to you, no games, and whisper, “Thanks for not giving up on me.”
Someone flirts with you? Kokichi fake-cries into your shoulder, stages a dramatic scene in front of the whole class, and then spends the rest of the day glued to your side. “I’m fragile. I need comfort. Forever.”
He’s terrified of being abandoned. He won’t say it directly, but you’ll catch him saying things like, “You’ll leave someday. Everyone does.” Reassure him often, he wants to believe you’ll stay.
Kokichi would secretly be the most loyal person ever.
Kokichi lies to the world but never to you, not about the important things. “I say a lot of dumb stuff, but when I say I love you? That’s the truth. The realest truth there is.”
He loves laying in your lap, burying his face into your neck, whining about how hard his day was (even if he caused it). He goes quiet after a while, just clinging to you like you’re the only real thing in the world.
He’s still a liar, but your liar.
“The world’s full of fake people and boring rules. But with you? I think I might actually want to be honest... at least sometimes.”
(Pause)
“Or not. Maybe I just want your snacks.”
I really hope you liked this! I'm open to request for pretty much anyone (from danganronpa or not!) so don't be afraid to ask!
