Park Shin Hye and Jung Yong Hwa (from the band C.N. Blue) reunite after their last hit drama "You're Beautiful" in this musical romantic comedy. Set in an arts college, Lee Gyu Won (Park Shin Hye) is a traditional Korean music major who is the granddaughter of a famed classical singer. Her grandfather pressures her to follow his footsteps and become the greatest traditional musician in Korea. On the other end, Lee Shin (Jung Yong Hwa) is a slacker but innately talented rock band guitarist. He has celebrity status in their school, but Gyu Won is completely unaware of him. When they clash over a gig that he was supposed to perform at, both decidedly hate each other. However, Gyu Won and Shin find themselves continually crossing paths, especially after joining the school's upcoming 100th Anniversary Performance. Will sparks of competition turn to sparks of young love? Acclaimed film and stage actor Song Chang Ui joins the cast as the Broadway director who comes to helm the 100th Anniversary performance.
