The episode begins with Nanno, the protagonist of the show, getting transferred to a new school. As she enters the school, she observes that this school is different from the previous ones because it is a high society school where the students belong to affluent families.

Nanno gets friendly with a girl named Yui who belongs to a wealthy family. Yui's family is extremely rich, and they have their own private swimming pool and other luxurious amenities at home. Nanno gets intrigued by this lavish lifestyle and starts admiring Yui for the privileges she enjoys due to her wealthy family.

However, as the episode progresses, Nanno begins to uncover the dark side of Yui's family and their lives. She learns that Yui's parents have a strained relationship, and Yui is neglected by both of them.

Nanno also comes across some other students in the school who come from broken and dysfunctional families. She realizes that despite the socio-economic differences, the students in this school are struggling with their own problems and traumas.

As the story unfolds, Nanno comes to know about Yui's hidden talent of singing, which she is afraid to showcase in front of her parents. Nanno encourages Yui to pursue her passion and gives her the confidence to perform in front of her classmates during a school event.

Towards the end of the episode, Nanno exposes the true nature of Yui's parents and their secrets, which shocks everyone. The episode ends with Yui realizing that she doesn't have to live up to society's expectation and can pursue her passion for singing despite her family's disapproval.
