It's Nanami Takahashi's second day at her new high school and almost as soon as school starts she quickly makes some new friends in her class, like the unsociable Yuri. A girl from Asahi middle school tells her about guy named Motoharu Yano, who was very popular with the girls and happens to be in their very same class. It isn't long until Nanami develops a crush on him, herself.

It is summer vacation and Nanami goes to school for the play rehearsals, but she's pretty annoyed that Motoharu doesn't turn up to any of them. Even at the summer festival he doesn't turn up, so Nanami goes to his house to see him. Motoharu reminisces on his past relationship with Nana.
