Vol.11 Chapter 85: Aren't You Lonely Without Me Around, Senpai?
Our nameless—and spineless—hero (only known as "Senpai") is a second year high school student and loner who spends his afternoons at the Arts Club room. He attracts the attention of one of his schoolmates, a sadistic freshman girl named Nagatoro. However, in between the bullying and teasing, something else begins to blossom. A lovey dovey(...?) story between a shy nerd and an S-Dere (Sadistic Tsundere) begins.
