Golden Time Season 1 Episode 6

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.
