Our nameless - and spineless - hero attracts the attention of one of his classmates, a sadistic young girl named Nagatoro. However, in between the bullying and teasing, something else begins to blossom. A lovey dovey(...?) story between a shy nerd and a S-Dere (Sadistic Tsundere) begins.
Loosely based on doujins which were released prior to the serialization of the manga.
