On his way back from school, Syusuke comes upon a group of boys tormenting a young elementary school girl. Syusuke chases the boys off, and the next day, the girl, Hinako Mochida, thanks Syusuke. Shortly afterwards, Hinako meets Sana at a restaurant and reveals her infatuation with Syusuke. With Aoi's aid, Hinako attempts to court Syusuke, but despite her efforts, is rejected by him. Despite this, Syusuke reveals that he considered Hinako an adult, which Hinako tearfully accounts to Sana, noting her satisfaction nevertheless.

As Nanaka contemplates how to apologize to Sana, she goes into shock after accidentally burning the fish she was cooking, bringing her close to recollecting memories of the fire that consumed her house. She then overhears a discussion between her uncle and her aunt hinting that her uncle was the one that caused the fire. The next day, the group goes to a theme park, where they meet Asami and her cousin. After viewing a tokusatsu show, Nanaka gathers enough courage to talk to Sana. As they ascend in a ferris wheel, the two reconcile. In another car, Syuri and Syusuke angrily argue over their stepmother, and Asami accidentally catches a glimpse of Syuri's saddened face.
