• He’s not over-the-top with PDA, but his hands are always on you. A thumb on your hip when you’re standing next to him. A palm on your lower back when you’re walking through a crowd. It’s never loud, but it’s always there.
• When he talks to you, his voice naturally drops. He doesn’t do it on purpose, but when it’s just the two of you, it sounds deeper. Slower. Almost lazy. You live for it.
• He listens more than he talks. But when he does speak? It’s something sharp, soft, or too honest—“You looked so good today I forgot what I was doing for a second.” And then he’s back to sipping his drink like he didn’t just mess you up.
• Yu likes having you close, but he’s not clingy. He’ll sit next to you in silence for hours—legs brushing, pinky hooked around yours—completely content. But if you shift away, he notices. And pulls you right back.
• He’s observant as hell. You don’t even have to say you’re upset—he’ll see it. “What happened?” No fluff. No pressure. Just the space to let it out if you want to.
• You steal his clothes and he lets you—doesn’t even say anything. But if you wear something of his out, he’s watching you all night. Doesn’t hide it. He likes it when people know who you belong to.
• He’s quiet until someone flirts with you. Then his hand finds your thigh under the table, firm grip. “They done?” he’ll ask without even looking. Just calm. Sure of himself. Sure of you.
NSFW
• Yu doesn’t just have a high sex drive—he has stamina. Quiet, unshakable, lethal stamina. One round is never enough. He’ll pull out, flip you, slide back in, and say, “Not done,” like you didn’t just come twice already.
• He’ll keep you on the edge on purpose. Fingers deep, lips brushing your ear, voice flat: “Don’t cum yet.” And if you do? He pulls away and leaves you twitching, overstimulated, untouched, until you’re begging again.
• When you ride him, he watches everything. Doesn’t touch—just lets you use him, arms behind his head like it’s nothing. “Go ahead,” he says, like he’s letting you work for it. Like he knows you’ll fall apart first. You always do.
• He likes holding you down. One hand locked around your throat—not squeezing, just firm. Thumb under your chin to keep your eyes on him. “Look at me,” he says while fucking you slow. “That’s it. Watch yourself fall apart.”
• He spits in your mouth sometimes. No warning. Just leans in, thumb on your chin, and lets it drip. “Swallow.” His voice doesn’t change—but your whole body does.
• Yu’s the type to edge you with just his fingers until you’re sobbing, then press his forehead to yours and whisper, “One more.” And you give it to him. Even when it hurts. Even when you’re shaking. Especially then.
• He’ll cum on your stomach just to watch it drip. Rake his fingers through it. Drag it across your clit to keep you sensitive. Then slide two fingers back inside like, “Still open for me. Good girl.”
• When you’re too fucked out to answer, he smirks. Slaps your thigh once—light but firm. “Use your words.” And if you still can’t speak, he slows down. “You want more?” Another stroke. “Say it.” Another. Until you do.
• And afterward? He doesn’t rush to clean you up. He spreads you open with one hand and just stares, lips parted, breath calm. “You should see yourself right now.” Then dips his fingers back in just to feel it one more time.
• The filthiest part? He doesn’t gloat. Doesn’t go breathless or wild. He ruins you with the same quiet intensity he does everything else—focused, steady, and completely in control.
