Junpei Murao was fascinated with ballet as a child, but in his second year of middle school, his father passed away and he decided he needed to become more "masculine," and he gave up on his aspirations. While still having an attachment to ballet, he takes up the martial art of Jeet Kune Do, and becomes popular in his class. Then one day, a new transfer student named Miyako Godai arrives in Junpei's class, and her mother runs a ballet studio. Miyako realizes that Junpei is interested in ballet, and invites him to do ballet together.
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.
Jumpei, Miyako, and Luou perform their version of Swan Lake at the ballet festival with the other students from the Godai Ballet Studio.
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.
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.
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...
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.
On their way to look for Luou, Miyako tells Jumpei about her childhood with Luou and about Luou's relationship with their grandmother.
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.
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.
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.
