Itoshi Rin

You never expected Rin Itoshi to even notice you. He was always so focused, so intense, so wrapped up in his rivalry with his brother and his obsession with becoming the best striker in the world. But somewhere along the way, something shifted. You started appearing in his vision more often, distracting him during practice, occupying his thoughts when he should’ve been strategizing. At first, he hated it, hated you for breaking his concentration. But hate turned into something darker and more consuming, and by the time he realized what was happening, it was too late. He was obsessed.

It started small. Rin would watch you from across the room, his teal eyes tracking your every movement with an intensity that made your skin prickle. Then he started appearing wherever you were—the gym, the cafeteria, the convenience store at midnight. “Do you live here or something?” you finally asked, half-joking, but his response was dead serious. “I go where I want. Not my fault you’re always in my way.” Except it wasn’t coincidence. He’d memorized your schedule, learned your habits, restructured his entire routine around yours.

The real problems started when other people got involved. Someone complimented your outfit and Rin was there instantly, positioning himself between you. “They’re busy,” he said flatly, and something in his tone made the person back away immediately. A classmate asked you out and the next day they showed up with a black eye, refusing to say what happened. Your friend who’d been texting you constantly just stopped. When you demanded answers, Rin finally snapped. “You want to know? I told them to back the fuck off. Made it very clear you’re not available.”

Someone bumped into you accidentally in the hallway. Rin was there instantly. “Watch where you’re fucking going!” His eyes were wild, hands already moving to shove the person back. “Rin, it was an accident—” you tried, but he cut you off. “I don’t care! They touched you!” His hands were on your shoulders, checking you over frantically. “Are you okay? Did they hurt you?” When you said you were fine, his grip tightened. “You’re not fine. You could’ve fallen, been injured. I can’t—I can’t let anything happen to you.”

It escalated. Someone talked to you too long at practice and Rin intervened aggressively, getting in their face until they backed off. “What the hell is wrong with you?!” you confronted him afterward. He grabbed your wrist, pulling you close. “What’s wrong with me? I think about you every fucking second! Every breath! You’re all I think about and I can’t make it stop!” His voice cracked. “I can’t eat, can’t sleep, can’t function without knowing where you are, what you’re doing, if you’re safe!”

You tried to establish distance but Rin wouldn’t allow it. He showed up at your apartment at midnight, pounding on the door. When you refused to open it, his voice cracked with desperation. “Please. I just need to see you. I haven’t seen you in two days and I’m losing my mind.” You made the mistake of opening the door and he was on you immediately, his hands on your face, trembling. “Don’t do that again. Don’t ignore me. The thoughts get too loud when I can’t see you.”

Someone made the mistake of flirting with you in front of Rin. They were hospitalized within hours. When you confronted him, there was blood on his knuckles and zero remorse. “He touched you. Put his hand on your waist like he had any right.” His voice was eerily calm. “So I made sure he’d never touch anyone again.” You felt sick. “Rin, you can’t just—” He cut you off, stepping close. “Yes, I can. I will. Anyone who tries to take you from me? I’ll destroy them. Completely.”
