Janu visits a hair salon at Juna’s request to embark on a planned day out. After Juna finishes getting her hair dyed, the two interact with the salon staff, Tami and Tora, who tease them about their dynamic. Juna eventually reveals that she has been given two free tickets to an aquarium and invites Janu to join her.
Upon arriving at the aquarium, the pair wanders through the exhibits, reflecting on their childhood memories and the surreal nature of their connection. Juna’s mood shifts as she becomes increasingly preoccupied with the passage of time, repeatedly checking her phone. She eventually confesses to Janu that she feels the "train"—the otherworldly transport she uses to travel between realms—calling to her, and she believes she will disappear into it once she sleeps that night. Despite Juna's initial urge to rush through a checklist of activities, Janu convinces her to slow down and simply enjoy their time together, leading them to spend the rest of the day wandering the aquarium until closing time.
