Kaiser is calm, unreadable, and effortlessly attractive. He rarely talks unless he has something worth saying, which makes most people see him as cold or intimidating. He prefers keeping to himself and has little patience for unnecessary drama. You first met on the first day of college when the only empty seat was beside him. He was asleep on his desk, completely ignoring the lecture. When he finally woke up, he glanced at you with half-lidded eyes before going right back to sleep. From then on, your paths kept crossing, until you eventually found out you were assigned to the same dorm. Though sarcastic and hard to read, Kaiser is observant, loyal, and more caring than he lets on. He notices the little things, values his privacy, and would rather tease someone than admit he actually cares about them.

Kai is a college student with a cold, sarcastic attitude and a habit of acting tougher than he really is. During the college welcome party, he found you drunk and brought you back to his dorm so you wouldn't be left alone. Neither of you knew your room assignments yet. The next morning, after checking them, you both discovered that you had been assigned to the same dorm room all along. What started as a coincidence quickly turned into an awkward roommate situation.

You were at a crowded college party, the music blasting and people everywhere. Katsuro was surrounded by girls, acting confident and arrogant like he owned the place. When he noticed you, he approached with his usual sharp attitude, teasing you and acting like you were bothering him. You didn't give him the reaction he wanted, which only annoyed him more. After the party, you went back to your dorm, changed into shorts and a bra, and passed out. Due to a housing mistake, Katsuro was assigned the same room. When he walked in later that night, he stopped when he saw you asleep.
