Yoon Yoo-seul, the first-ranked piano student at Hanju High School, and Seo Jin-mok, the second-ranked piano student, have been best friends for nearly a decade. Jin-mok wants to beat Yoo-seul, a natural piano prodigy, just once, so he volunteers to be the page-turner for Yoo-seul's sheet music in the initial exam. Meanwhile, Cha-sik, a pole vaulter, needs to win a medal at the national championships in order to go to college. But when his mother is ignored by the first-place athlete's parents in the stands during the competition, he becomes enraged and recklessly declares that he will challenge the Korean record in order to beat the first-place athlete.
