Ep. 17: Banri prepares to return home while friends uncover secrets about his past and amnesia.

Banri visits the Golden Time restaurant, where the Festival Club acts unusually kind, leading him to believe they are consoling him over a supposed breakup with Kōko. When Kōko arrives, the misunderstanding is resolved, though former fourth-year members create further confusion. Linda joins late, and the trio discusses a past accident, with Linda providing vague answers about how she learned of it. She asks if Banri plans to return home, and after Kōko decides for him, the couple reflects on their recent fight and their deepening love. Banri departs the next day on a train. Meanwhile, Chinami invites Kōko to help unpack and stay overnight, eventually expressing admiration for Kōko’s devotion. At Linda’s workplace, Mitsuo discovers her train ticket matches Banri’s destination, causing Linda to leave angrily. Later, Mitsuo and 2D speculate about Banri’s amnesia at a cafe, while Kōko deflects their inquiries, leaving Mitsuo to ponder the new information.
