Lee Shin is a university student majoring in modern music. He is also
the vocalist and guitarist of the band "The Stupid." Shin is known for
his good looks, cocky personality, and strong passion for music.
Everyone sees him as a cold-hearted person, but he's actually soft
inside. He lacks interest in anything unrelated to music and has neither
dreams nor plans for the future. He initially likes Jung Yoon Soo, a
dance professor at university, but this all changes when he meets Lee
Gyu Won.
Lee Gyu Won is a bright and outgoing student who was born into a
prestigious family and is majoring in traditional Korean instruments,
especially the gayageum. Gyu Won's grandfather, Lee Dong Gun, is one of
the top 3 traditional musicians of his age and his biggest wish is to
see his granddaughter become a traditional music prodigy. Trying to live
up to her grandfather's expectations, Gyu Won immerses herself in
training and becomes a university student who knows nothing outside of
her studies. As her friends are fans of "The Stupid", she was forced to
go to the band's concert with them. There she saw Lee Shin performing
live, and is immediately captivated by him.
