In a dream, Banri remembers that after his love confession to Linda, she agreed to tell him her response the following night on the bridge where Banri would have his accident. Kōko notices Banri's unusual behavior around Linda, but when she questions him, he denies that anything is wrong. Chinami finds the two and invites them to a party, but Kōko declines out of dislike for Chinami, but this does not dissuade Chinami, who explains to Banri that she likes Kōko. Banri convinces Kōko to attend, alongside Mitsuo and Nijigen, but Kōko and Mitsuo end up arguing about Chinami, which ends with Mitsuo confessing to Chinami, and her turning him down. On their way home, Banri decides to end his friendship with Kōko, due to her lasting infatuation for Mitsuo, and despite Kōko's objections, he leaves her. The next day, Linda notices the tense atmosphere between the two, but when she inquires about it, Banri confronts her about not telling him that they previously knew each other. Linda explains that she said nothing out of fear of confusing him and driving him away, while also admitting her guilt in feeling that she had caused Banri's accident by not responding to his confession sooner. Afterwards, Kōko meets up with Banri to learn what happened, but he takes off running due to the revelation that Linda might have reciprocated his feelings years ago, and how her answer would have affected his life. Before he can wonder if having the same accident would let him do things over again, Kōko manages to catch up to Banri and tells him not leave her, confessing that she loves him.

Stunned by Kōko's words, Banri waits for Kōko where she had rejected him, hoping Kōko would come back. Hours pass and Banri meets Kōko's father, who drives Banri home. Along the way, Banri deduces that Kōko may already had knowledge of Banri taking anti-anxiety medications and asks her father about the diagnosis that leads to its prescription. Later Banri encounters Nana. Banri confides in her about his recent dilemma. The next day, encouraged by Nana's words, Banri plans to confront Kōko. Afterwards, Banri meets Kōko, seemingly acting the same whenever the two interact. However, after meeting their friends, Kōko nonchalantly declares that she and Banri are broken up, much to the shock and bewilderment of Banri and the others. After Kōko lashes out, Chinami tells Banri that Kōko may have seen the clip of Banri's anxiety attack. Staying optimistic, Banri later informs Linda and the president of the Festival club of his breakup with Kōko. Banri and Linda argue. Banri reveals to Mitsuo his past relationship with Linda and apologizes for not telling him. Kōko then appears as she hands down a letter of resignation from the club to its president until Banri cuts her off, causing her to leave with Banri calling out to Kōko.
