The episode begins with Hayakawa expressing her desire to take a trip to the hot springs. Shinozaki hesitates at first, but her supervisor encourages her to take a break since there isn’t much work to do. They decide to go on the hot springs trip together with their supervisor and Katase, Shinozaki’s superior.

When the group arrives at the inn, they excitedly discover that there’s a pool. Hayakawa and Shinozaki are particularly curious about Katase’s swimsuit choice. However, Katase surprises them by opting for a more mature style. While enjoying the pool, Shinozaki learns that Katase can’t swim. He offers to teach her, but the lesson is interrupted when Shinozaki gets a leg cramp. Katase rescues him, and in the process, she swims for the first time.

Later, the group enjoys dinner, during which Katase gets increasingly tipsy. She insists on taking care of Shinozaki, leading to some awkward moments. Hayakawa and the manager decide to leave the two alone and take another dip in the hot springs. Meanwhile, Katase’s drunken antics continue, and Shinozaki struggles to handle the situation.

Suddenly, Hayakawa and the manager return, convinced that the inn is haunted. They heard noises coming from the closet where Shinozaki and Katase had hidden to avoid being discovered in their embarrassing predicament. The episode ends with the group settling down and reflecting on the day’s events. Katase falls asleep but still clings to Shinozaki’s hand, leaving him in a complicated emotional state.
