Yoshida Miake is a charismatic first year high school student who is in love with her best friend whom she has known all of her life. The only problem is the fact that he has no interest in her whatsoever. Heartbroken, she finds comfort from "Mr. Black" and slowly begins to develop feelings for him. But how can she develop a relationship with a person who exchanges kisses for lunch?
