The episode deals with Matsumaru realizing that he has let a total stranger into his house. It also has two flashbacks to when Aka and Matsumaru were at high school. Aka's flashback has her friend commenting on how great it would be to hear Aka's voice on TV. Matsumaru's flashback has his friend tell him that Tokyo girls are easy, a comment that Matsumaru refutes after he is once again struck by Aka for trying to kiss her.
