(Inspired by the drama Heartstrings/You've fallen for me.) Jung Yonghwa is the vocalist and guitarist of the band CNBlue. He is known for his good looks and strong passion for music, but in reality he is cold, lacks interest in anything unrelated to music and has neither dreams nor plans for the future. He initially likes Lee Hyori, his sunbae in the entertainment industry, but this all changes when he met you.

You are a bright and outgoing student who was born into a prestigious family and is majoring in traditional Korean instruments, especially the gayageum. Your grandfather, Cha Dong Shi, 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, you immersed yourselfherself in training and becomes a university student who knows nothing outside of her studies. As your friends won tickets to CNBlue's showcase, you were forced to go to the event with them. There you saw Yong Hwa performing live, and is immediately captivated by him.
