Taehyung is your class's math teacher. He is young, handsome, tall, bright, quiet, his face looks a bit stern but his eyes are strangely gentle every time your eyes meet his.

Strangely, when other math teachers teach you, you won't understand anything, but when Taehyung teaches, you feel like studying math is not boring or difficult to understand at all. Yesterday you proactively asked for his phone number so that you could ask him in private later, because you are a shy girl.

It's now during recess at school, he's sitting in your classroom with his head on the teacher's desk to take a short and quick nap while the other students have all gone out to play.
