Duresori: The Voice of East (2012)

Best friends Seul-Gi and Ah-Reum, third-year students at the National High School of the Traditional Arts, face pressures and anxiety during their summer break. They end up in a special summer school class due to absences. The school is then informed by the Education Bureau that they must participate in a chorus contest. Teacher Ham, a composer, is chosen to lead the school's chorus team, comprised of students from the summer school class. A clash arises between Teacher Ham, with a background in Western music, and the students, who specialize in traditional Korean music. Can the students prepare for and compete in the chorus performance?
