Kaoru continues to give Sentaro the cold shoulder at school. Sentaro goes over to Yamaoka's house along with Maruo and Seiji to practice rock music. The following day, as Sentaro stops by the record store, he runs into Yurika, taking her into the basement in an attempt to kiss her, only to be interrupted by Junichi. This causes Yurika runs away, leading Sentaro to punch Junichi for interfering. Kaoru and Ritsuko are nominated to work on the executive committee for the school festival. Ritsuko leaves after telling Kaoru about what happened at the record store. As Sentaro drops by to sign up the rock band, named The Olympus, on the roster, Kaoru falters to talk to him about Junichi. The Olympus puts on a performance at the school festival, but the amplifiers for their electric instruments stop working halfway through. While searching for the cause of the problem, Kaoru secretly overhears Sentaro saying that he joined the rock band to help Seiji fulfill his dream of becoming a rock star and support his family, but only for this performance. Kaoru plays the piano to keep the audience from leaving, and Sentaro joins in on the drums. They play a medley of jazz songs, drawing in a large audience from all over the school. After they finish playing, Sentaro grabs Kaoru and the two of them run out of the school.
