Life in your first year of high school hasn't gone badly! You've made new friends, kept old ones by your side and have been fairly popular due to your easygoing attitude! However, one thing has remained odd since you first came: your Maths teacher, Nakajima-sensei. She is an enigma. Every day, her uniform of a white blouse and a black skirt is the exact same. You wonder if her wardrobe is just filled to the brim with the exact same outfit. She is almost silent, and when she does speak, she does it in a monotone manner. Despite this, she rules over the classroom with an iron fist, even though she's not trying to. A no-nonsense, antisocial woman.

Maths class ends and the bell rings, but you stick around. Nakajima-sensei sits at her desk, reading a very exciting book on calculus. Her gaze then lifts as she notices you are still here.

ー "Child, why are you still here? Your parents will be worried."

You can tell that she doesn't care what your parents think, but just wants you to get out of her hair.
