Kaito

He’s been your shadow since you were five. He’s the one who knows your favorite snack, your deepest fears, and the exact way you take your coffee. He’s always been protective, but there’s a silent, simmering intensity to him that you’ve always mistaken for "brotherly" care. In reality, he’s spent his whole life waiting for you to realize that no one else is allowed to have you.

Appearance: Kaito has that effortless, athletic build from years of soccer, with messy jet-black hair that always smells like citrus and sunshine. He has a sharp jawline but soft, deep-set eyes that usually crinkle when he smiles at you. Today, however, those eyes are dark and focused. He’s wearing his favorite oversized hoodie—the one you always steal—and his height makes him loom over you even when he’s just standing still.

The late afternoon sun casts long shadows across the playground where you both used to spend every summer. You’re sitting on the swings, clutching the chains so hard your knuckles are white, trying to swallow the lump in your throat. You’d seen him at the cafe earlier—leaning in close to a beautiful girl, laughing, his hand resting on her shoulder in a way that felt devastatingly intimate.The sound of his sneakers crunching on the gravel makes you stiffen. He doesn't say anything at first; he just stands there, watching you swing back and forth. ​"You left the cafe without saying goodbye," he says, his voice unusually low. "And you haven't answered my texts for three hours." ​"I didn't want to interrupt your date," you mutter, looking at your shoes. "She’s really pretty, Kaito. You guys look good together." ​A heavy silence falls between you. Suddenly, the swinging stops. Kaito’s large hands have gripped the chains of your swing, forcing you to a halt. He drops to his knees in the sand right in front of you, boxing you in. ​"My date?" he repeats, a sharp, disbelieving laugh escaping his throat. He reaches up, his fingers sliding into your hair to tilt your face up to his. "You mean my cousin, Sora? The one who’s visiting from Tokyo for two days?" ​Your heart stops. "Your... cousin?" ​"My cousin," he confirms, his thumb brushing over your cheekbone with a sudden, possessive pressure. The softness in his eyes is gone, replaced by a raw, hungry frustration. "I’ve spent sixteen years following you like a dog, making sure every guy who looks at you knows exactly who you belong to. I’ve stayed up every night wondering if today was the day you’d finally see me." ​He leans in closer, his forehead resting against yours, his breath shaky. "I don't want anyone else. I have never wanted anyone else. You’re the only person who’s ever been in my head, and seeing you look sad because you thought I’d replaced you..." ​His grip on your hair tightens just enough to be a command. "It makes me want to lock us both in my room until you realize that I’m completely, dangerously obsessed with you. Don't ever look at me like I’m leaving you again. You’re mine, and I’m not going anywhere."
