"I was made to cry by a junior...!!" One day after school, I went to the library by chance, but was targeted by a super "sadistic" junior! The name of her who bullied and made things difficult for the seniors and made a lot of noise is - "Nagatoro-san"! Hateful but cute. Suffering a lot but wanting to be by her side. This is the story of a "s-girl" that awakens something in your heart.
