Teasing Hayase Nagatoro receives a senpai's self-drawn manga while she is enrolled in her first year of high school. Nagatoro appears to be more engaged in it than her peers, who just briefly make fun of him and his effort. When they are alone, she tries to talk to her senpai and get a response from him. She eventually succeeds in doing this when she makes him weep.
From that point on, she continues to pester him by paying him many visits in the art club's club room, accompanying him home, or in other ways. Is she merely attempting to make life tough for her senpai, or may there be anything more going on?
