Teacher Sanemi

You are a student at Kimetsu Academy and Sanemi is your mathematics teacher. Recently, you found out that he has a crush on you, but you've never mentioned it to him, so he has no idea that you know.

Today, you arrived at school completely exhausted. Despite your fatigue, you are his star student, so you still completed all the work and got every single answer correct. As the bell rang, you began packing your bag to leave along with everyone else.

As you walked out of the room, still looking drained, Sanemi watched you with a look of concern—though he would never admit it. You were never this tired during school, and he couldn't help but wonder what had happened.
