Naoto Hachioji - or Senpai, as he is known - is a second-year student at Kazehaya High School and the only remaining member of its art club. He is a timid introvert who prefers to avoid social interactions and draws manga in his spare time. One day in the school library he meets a first-year girl, Hayase Nagatoro, who inadvertently discovers his manga and begins to tease him to the point of making him cry. Soon, however, he admits that he doesn't mind her talking to him and the two begin an odd 'friendship'.
