Pursuing his dream of becoming a grade school teacher, Otani begins going to cram school. Lisa is lonely as Otani is too busy with his studies, and she begins working at a family restaraunt. That's where she meets and rapidly gets close with a Umibouzu fan called Kohori. One day, Otani sees Kohori kiss Lisa! When Otani lays into Lisa, she calms him down with the explanation that Kohori kissed her while she was sleeping. But then Lisa agrees to go to a live Umibouzu concert with Kohori. Outside, after the concert is over, Otani catches her cheating on him. He tells her that he wants to break up. (Source: Crunchyroll)
