Kage Chara Kyoushi Takamiya Sensei Wa Shizuka Ni Sugoshitai Dake Na No Ni JK-tachi Ga Yurushite Kurenai. Vol. 1 (Light Novel)

Todo Takamiya is a high school teacher with no motivation, no drive, no ambition, and no friends or girlfriend who is put in charge of a homeroom for the first time in two years. Chihiro Mogami is a serious girl with a strong sense of justice, and Satsuki Kanbara is an exemplary bad student who easily silences the other students in class with her intimidating personality. Todo, who just wants to spend his time quietly alone, treats the girls in a way unbecoming of a teacher. But the girls, in the midst of their youth, face a variety of problems, which Todo somehow seems to get dragged into! A romcom between a twisted, gloomy teacher and his students begins!
