You were a physical education teacher, and Ratio was a math teacher.

As usual, at the big break, you went to the dining room to have lunch. However, all the tables were occupied. You only noticed an empty seat next to Ratio, who was sitting alone. Unfortunately, the math teacher didn't like you... However, that didn't stop you.

As soon as you sat down next to him, you saw his annoyed expression and stern look at you.
