This episode mainly takes place during a class trip. The students are asked to sit with classmates they don’t normally interact with during the bus ride, leading to some unexpected pairings. Interestingly, Kasahara ends up with Takada, and Nishimura finds herself paired with Umi.

During the bus ride, Takada starts feeling carsick. As a result, the class is forced to leave him behind for a while. When Nishimura sees this, she offers to stay with him, showing her caring side. Her willingness to stay with him significantly changes the dynamic between the two and gives them a chance to spend time together.

Their detour becomes an opportunity to break from routine, allowing them to interact in a relaxed setting, free from the usual group dynamics. They visit a pharmacy, enjoy parfaits at a local bakery, and even share a mischievous moment when they spend the money their teacher gave them on snacks instead.

Meanwhile, Nishimura’s lunchbox becomes a highlight of the trip. The marinated eggs in her lunchbox become a topic of conversation among the group and lead to an unexpected food exchange among her friends. Sharing and swapping food not only reflects a common cultural practice but also helps forge connections and build relationships.

Back at the space museum, Nishimura talks about her love for space, a passion instilled in her by her father, who took her to the planetarium as a child. The group’s exploration of the museum sparks lively discussions, with each friend contributing their own enthusiasm and curiosity.

In the end, Nishimura receives a souvenir voucher and decides to bring something back for her father.
