The show begins with a young high school student, Yoon Sewell, waiting in the car for her mother, listening to pop music. When her mother arrives, she changes it to classical piano music, revealing Yoon's upcoming piano competition. Her mother is determined for her to win. Yoon's mother suggests she be the page turner for her opponent, Jinmock, to disrupt his performance. Yoon follows her mother's advice at the competition, helping Jinmock maintain his tempo by turning the pages at the right time, despite feeling dismayed.
