Banri has a dream of himself, apparently injured, fleeing from a hospital, but upon awakening cannot remember any more than that. Arriving at the university gate, he meets Kouko, who is waiting for Mitsuo, and the two talk some more. He notices that Kouko seems lonely without Mitsuo. Later that night, he tells Mitsuo about Kouko, but Mitsuo brushes it off, saying Kouko is just acting to get Banri to bring her to him. To brighten the mood, Mitsuo invites Banri to the Film Club's welcoming party, where club member Chinami got Mitsuo to join. The party was soon crashed however by the Tea Club's party, who drag Banri off to join in their festivities. He meets a new friend Takaya Satō, nicknamed Nijigen. The next day, Banri notices that Kouko has still not made any friends, and encourages her to join a club. Another student overhears them and invites the two to a café to tell them about her club, which lasts until dark. She invites them on her club's overnight trip to see if they would be willing to join. Still wanting to help Kouko, Banri decides to accompany Kouko when she agrees to go.

On the day of the scheduled club trip, Banri meets with Kōko and Nijigen, who is also invited. When the club members arrives to pick up the attendants, Banri becomes suspicious of them when he notices they all wear a similar pendant, and more so when they bring the group to a remote location. The club then reveals itself as a cult who wishes for Banri's group to join them. Banri convinces them to let the others go, when he tells them that he suffered an accident after high school that gave him amnesia of everything from before starting college, and that they could help him. As the others leave, Kōko decides to stay with Banri, and the two ultimately escape and hide in the woods. As they hide, Banri and Kōko bond by getting to know more about one another. Kōko reveals she was actually a nice person, and only acts stuck up around Mitsuo due to her feelings for him, while also confessing that she really was just using her friendship with Banri to get closer to Mitsuo. Banri in turn reveals that his story about having amnesia was not a lie, and that he feels that his family and friends want the current him to disappear and have the old him return. While he sympathizes with their wishes, he does not want to lose his current self. When the pair hear the cult members looking for them, they flee further into the woods, until they are found by Linda.
