After entering high school, Yume was making an effort to change her personality and looks in an attempt to reinvent herself as a model student. It was all so far so good, but there was one thing she couldn't change about herself. She was never very athletic. On the day of the physical fitness test and body measurement check at school, a melancholy Yume is approached by Minami Akatsuki, a girl from the same class. Meanwhile, Mizuto is as disinterested as ever...

The first midterms of the school year are upon them. Once the top scoring student in the school's entrance exam and now a talented student at the top of her year, Yume is anxious to defend her position as a model student. She is displeased, however, to discover Mizuto’s relaxed approach to studying. The two later butt heads again, over something Mizuto did during their Japanese exam. Yume berates Mizuto for his actions while Mizuto retaliates in kind.

Due to their mutual interest in light novels, Isana considered Mizuto a dear friend. However, Yume and Akatsuki make her realize that her feelings for him may run much deeper than that. Now aware of her true feelings, Isana wishes to become Mizuto's girlfriend. Unfortunately, he doesn't seem to be reacting to her advances. Yume and Akatsuki try to give her advice, but it doesn't quite go according to plan.

Still in the countryside visiting relatives, Yume and Mizuto head to the local summer festival together. In high spirits from getting to see him in his yukata and seeing how Madoka and Chikuma interact as siblings, Yume boldly takes his hand in hers as they walk around the festival stalls. During their outing, Yume begins to get a picture of how Mizuto was as a child. And in doing so, realizes just what his meeting her meant to him.
