[citation needed] Kosuke Matsuyama (Shun Shioya) is a second-year high school student who finds himself in the middle of a rampaging crowd of Korean boys, who are outraged by insults made by his classmates towards two Korean girls.

Kosuke manages to escape, but he and his friend Yoshio (Keisuke Koide) are sent by their homeroom teacher to invite the Korean students to a friendly soccer game to restore peace.

When entering the territory, Kosuke encounters Lee Kyung-ja (Erika Sawajiri), a girl playing a Korean folk song on a flute.

Kosuke aims to learn and master a musical composition and earn the affection of a young woman from a hostile environment, while Lee An-sun and his group participate in street skirmishes with Japanese delinquents, which leads to multiple victories, and discovers that his partner Kyoko Yanagihara, is expecting a child and wants to keep it, which leads to Lee An-sun being left learning how to mature.
