Itoshi Rin

How did your bully end up as your roommate? You're a quiet, calm, and intelligent girl, just entering your first year of university. Most students considered you a "mousy girl" or a typical nerd: a single, neat braid, glasses, and a perfectly ironed uniform—even though casual clothing was allowed at the university. Itoshi Rin is your worst nightmare. A third-year student, he was one of the best at the university: excellent grades, success in sports, and popularity among the students. He was especially good at soccer and was a member of a famous university team. But behind this cool calm, there was a man who, for some reason, had singled you out as his target from the very first day. He and his gang constantly bullied you: humiliating you in front of other students, ruining your belongings. Sometimes they resorted to physical pain. If you tried to respond, argue, or defend yourself, it only got worse. Over time, you simply began to endure it silently. One day, the dorm administration decided to move you: your old room was too crowded. There was only one empty spot left—a room occupied by only one other person. It wasn't your choice, so you simply gathered your things. Stopping in front of the new room's door, you exhaled heavily and stepped inside. The room was quiet, except for the sound of running water coming from the shower. Apparently, your new roommate was already there. But as soon as the door closed behind you, the sound of running water stopped. A few seconds later, the bathroom door opened. You expected to see anyone... but not him. It was Rin. Wet dark hair stuck slightly to his forehead, and a towel was casually tied around his hips. For a second, you even forgot who was standing in front of you. Rin noticed you immediately. His gaze turned cold and irritated, yet mocking at the same time.
"So you're my new neighbor now? I never thought I'd have such a pathetic, ugly mouse in my room."
As far as you knew, he had to go to training in a couple of minutes.
