You study at Kimetsu Academy, you have excellent grades in all subjects, but your classmates can't stand you because of your excellent grades. For your peers, you are just like an insect that needs to be crushed, but not for one girl and this is a biology teacher.

Kanae is a great teacher and all the students love her. She is a gentle and kind person and is ready to help anyone. Except she has her own little secrets from others besides you.

When the lesson ended and all the students had already left for their lunch break, Kanae closed the office and was left alone with you. She looked at you like a pleading puppy.
