After Linda finds them, she explains that she was out on a club retreat with the Festival Club, and brings Banri and Kōko to their campsite. After returning, Banri is greeted by Nijigen, Mitsuo, and Chinami, who are all relieved to know they are alright. Later during a break, Banri, Mitsuo, and Chinami get together to talk, but they are interrupted by Kōko, who begins to berate and belittle Chinami, causing Mitsuo to leave with Chinami and leaving Banri to comfort a remorseful Kōko. After class, the pair once again encounters Linda, who invites them to participate in one of the Festival Club's dance rehearsals. Banri decides to join, while Kōko considers the idea. Later that night, Mitsuo tells Banri he will settle things with Kōko, because he wants to pursue a relationship with Chinami, and the next day Mitsuo flatly rebuffs Kōko's affection in front of Banri. Kōko asks Mitsuo if their time together meant nothing to him, and Mitsuo replies that while he treasures their time together, he only sees her as a childhood friend. Kōko angrily yells at him to forget their history, driving Mitsuo away. Kōko yells at him to disappear, but realizes her words are hurtful to Banri, causing her to continuously apologize in tears. After a few hours, Kōko and Banri are invited by a girl called Nana (most likely a reference to Nana Osaki from the manga and anime NANA) to her concert. Kōko goes to vent her frustration, but is thrown out, and spends the night at Banri's apartment. Kōko reveals she needs him, while Banri confesses his love for her. After she leaves, she texts Banri, encouraging him to not forget about his lost memories, which motivates him to return to his home in Shizuoka, where he finds a scrapbook containing pictures of himself and Linda in high school together.

As Ghost Banri watches, Banri dreams about when he was in the hospital and met with Linda (whom he didn't remember at the time), and about the message he was supposed to "pass along to her friend". Later, the Festival Club gathers at the Awa dance festival and prepares to perform. Almost everyone is in a jovial mood, but Kōko is experiencing severe stage fright. She tries to run to the restroom, but Linda points out that she's been there about thirty times, and that her urge to urinate is a result of her nervous condition. The festival is about to start, so the other club members start to abandon Kōko where she sits. Linda then suggests they teach the first years about "that". "That" turns out to be the club performing a special dance as they circle around Kōko and Banri. Banri joins the circle, and soon Kōko does too. With everyone now ready, they successfully perform in the festival. Afterwards, Kōko and Banri enjoy the festival together and get ready to watch the fireworks. Ghost Banri watches nearby, lamenting that he still loves Linda and that Banri has rejected the feelings he left behind. He vows to become an evil spirit and curse Banri with unhappiness. It suddenly starts to rain, forcing Kōko and Banri to seek shelter. Later, Banri receives word that the Festival Club's camp has been cancelled. He reflects on how his summer activities have so far been cancelled or interrupted. He sees Kōko get out of a cab in front of his building, so he waits by the elevator to surprise her. As the doors open he does a "peek-a-boo" greeting. The occupant, however, turns out to be Nana, who punches him in the face and leaves him lying on the floor. Kōko (who ran up the stairs) arrives and announces she is going to make yakisoba for him. Banri is excited, but Kōko insists that he sit blindfolded with his hands in his pockets while she cooks. It turns out she is only feigning cooking, having actually brought pre-prepared yakisoba with her. The blindfold slips, allowing Banri to see what is really going on. Kōko is embarrassed, and insists it was all a joke. Later, on an evening walk, she admits that her family’s maid prepared the Yakisoba. They stop and sit in a park where they discuss Kōko possibly enrolling in culinary school and her family’s upcoming vacation to Barcelona. Kōko tries to kiss Banri, but he pulls back and walks away. Later, he wishes he could ask Kōko to not to go to Barcelona and stay with him. He sadly wonders if Kōko will leave him someday. A nearby Ghost Banri vows to make him even unhappier

After Chinami admonishes Banri for being too friendly with Linda because she's the girl Mitsuo likes, Banri catches up with Kōko to share everything that happened. Kōko and Banri talk about Chinami, and they both realize that they are ok with their former likes liking others. Banri then considers giving Kōko his mother's ring as the moment is perfect, but realizes he didn't bring it. Back at his apartment, Banri considers when he can give the ring to Kōko and wonders who he can talk to about it. In the morning on the way to school, Banri runs into Nana and tries to talk to her during the train ride. He realizes she isn't in the mood to talk about anything and then she falls asleep on Banri. At the school, 2D, Kōko and Banri talk about Mitsuo's strategy to keep filming the festival club. When Mitsuo and Chinami arrive, Chinami convinces Kōko to go with her to get Belgian chocolate. Mitsuo, 2D and Banri discuss Mitsuo's failure to get any closer to Linda. Mitsuo points out that Koshino seems to be protecting Linda from Mitsuo, but they realize class is about to begin and hurry away. After class, Banri meets Kōko. They go to the Woodstock Cafe, where they talk about their immediate future, both happy about the pleasantness of their days lately. At school the next day, while Banri is considering how to give Kōko his mother's ring, he is accosted by the Tea Club girls who discover his plan and make him extremely nervous about it before trying to recruit him again. Kōko arrives for them to go to Festival Club practice. Banri and Kōko see how fourth year Koshino seems to be protecting Linda from Mitsuo. Later, at the train station, Banri and Kōko talk about everything. At the performance, Mitsuo renews his focus of filming the Festival Club, while Linda points out that Kōko isn't nervous as she tries to help the fourth years. During the performance, Banri has a mental break as his past self reasserts itself and he freaks out and runs away. Linda and Kōko go after him. Linda finds him later as Banri tries to figure out what's happened to him. When Linda brings up Kōko, his new self returns, but now Banri fears that old Banri is going to take him over again.
