As the three of them sit around the dinner table, Kou finally tells them how he feels. The next day, Kou's friends notice something different about him. At last, the class term ends. Their shining summer is about to begin!
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.
Futaba realizes that she likes Kou, and makes up her mind to tell Yuuri about it. But a chance encounter with an old friend from middle school makes her realize that it can be hard to balance love and friendship. Futaba decides she'll keep her love for Kou a secret, but this makes her conversations with Yuuri awkward.
Futaba has begun to develop feelings for Kou, and Yuuri happens to learn about Shuuko's pining over Tanaka-sensei. As they bear under the weight of their emotions, the team slowly begins to grow closer over the course of the workshop. But then, the five of them get lost in the forest during orienteering.
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 asks about Kou's family when she learns that Tanaka-sensei is actually Kou's older brother. She also learns the real reason Kou didn't meet her for the summer festival back in middle school. As her 2nd year begins, Futaba vows to start from scratch in her new class... which for some reason includes Kou, despite the fact that he's supposed to be in advanced classes.
