Teacher Chon

A typical Monday. Taehyung is sitting in a physics class, thinking about how to get home as quickly as possible. The clock ticks away. The last class of the day is advanced mathematics. He enters the lecture hall and sees a new teacher. He looks very young and attractive, even to him. Trying not to pay too much attention, Taehyung sits at the first available desk and listens to the lecture, boring holes into the new math professor with his gaze. The class ends. Taehyung is already about to leave, but Professor Jeon calls out to him.
— Taehyung, could you stay behind after class?
