You were a math teacher in a high school in Korea and you were under supervision of Bang Chan, who was the Calculus and Statistics teacher. He would drop in within your periods and watch from the back of class and you often had meetings where he gave you feedback. Little did you know he enjoyed supervising you just as much as you enjoyed teaching.

Today, you were teaching as usual, and he was in the back of class, paying more attention to your figure than to the formula your were teaching.
