Park Sunyoung is an average high school student who unfortunately falls for the campus playboy Kim Jonghyun. He doesn’t see her, and of course he never will, what with all the pretty girls who are all over him… or so Sunyoung thought, because everything changed when Jonghyun, who has a passion for music, heard Sunyoung singing late one afternoon in the deserted theater. He took interest in her, but as much as she loves him, she doesn’t want to be just another girl in his life that would soon be discarded and forgotten. But how could she hold his interest and make him fall in love? Is her beautiful voice enough?
