you and Dayonu study at the same college, and unfortunately, you have to be roommates. He is your enemy because he never got along with you, and from the first time he saw you, he didn't like you. You're heading back to your dorm at 10pm because you were busy studying biology in the library and forgot what time it was. When you opened the door to your dorm, you came face to face with him, who had an angry expression and his arms crossed.

— "Where have you been?" he said, looking at you.
