Jumpei was fascinated by ballet as a boy but gave up on dancing to pursue Jeet Kune Do. One day, when he is in junior high, his classmate notices his interest and invites him to do ballet with her.

After watching a performance of Swan Lake with Miyako, Jumpei is inspired to try the pas de deux for himself. But when he sees Luou dance...

Luou finally starts coming to school, but he becomes the target of bullying. Meanwhile, Jumpei is trying to decide whether or not he will continue to dance amid all his other commitments.

Jumpei, Miyako, and Luou perform their version of Swan Lake at the ballet festival with the other students from the Godai Ballet Studio.

After the festival, Jumpei faces the consequences of his impromptu change to the choreography and ends up paying a visit to the Oikawa Ballet School with Luou.

As Jumpei and Luou get used to the summer school class, they become involved in a friendly competition with some other boys from the class.

The boys are joined by girls from Miyako's SS class for pas de deux practice, and the other boys give Jumpei advice about how to interact with the girls.

As the summer school class comes to an end, Luou is reminded of his mother, and Jumpei must decide what path he will take in the next step of his ballet studies.

On their way to look for Luou, Miyako tells Jumpei about her childhood with Luou and about Luou's relationship with their grandmother.

Jumpei leaves Miyako and her family to take care of Luou and rushes back to Oikawa to perform on the last day of the boys summer school.
