Due to the negative impact of Westernization on her native culture, Lee Dan Ah becomes weary. On her first day of high school, she decides to break away from the regulated uniform and dresses in a traditional Korean hanbok. However, the principal, who holds progressive views, admonishes her for flouting school regulations. In order to pursue the idea of a hanbok uniform in school, Lee needs to gain the support of 70% of the student body and faculty within six months. Unfortunately, she fails to recruit the minimum requirement of five members to establish a hanbok club, making her objective unreachable.
