Futaba has volunteered to be class representative for her new class, and so has Kou. They're all set to participate in an overnight leadership workshop with event representatives Yuuri, Murao Shuuko, and Kominato Aya. However, a troubled start to their morning foreshadows anxieties down the road, and a bad vibe hangs over the team...

Futaba notices a change in the vibe between Kou and Yuuri during the study meeting. She really wants to ask Kou about it, but ends up skirting the issue. Instead, she tells Kou that she wants to know more about him. Kou shows her to a certain room. There, in silence room, Futaba realizes the reason why Kou changed.

While Kou was going to middle school in Nagasaki, he lost his mother to an illness. Futaba finally realizes the pain Kou feels over that sense of powerlessness. Hoping to open Kou's heart the way that Kou opened hers, she chases after Kou and desperately expresses her feelings to him.
