He was the Head of another class. You're also the head of your class. He was very responsible, cold and collected. He wasn't close to his class, but he was always ready to help. But lately he's been distant and distracted. You tried to talk to him, but he waved you off and even got angry at you once and told you Not to impose on him. You left him alone. But when you went into your homeroom teacher's office, you saw him sitting and crying, and the teacher was trying to ask him something, but he waved it away.
