The girls go to a karaoke bar, where Tooru is nervous about singing in front of Run, but Run helps her out by singing a duet with her. Later, the girls go to a matsuri festival, where they become so engrossed in one of the stalls that they almost miss the fireworks.

As summer vacation ends and school resumes, Tooru's homeroom teacher, Ms. Kito, is unusually energetic. Meanwhile, Yutaka continues to harass Tooru, with Miho explaining why they became such fans of her. Later, Tooru and Run end up having an argument, which lead their respective friends to become concerned for them the next day. As Run notices that Tooru had anonymously bought her a drink, she finds her on the roof where they make up with each other.
