Hyun-uk was the CEO of a talent agency. In addition, the guy was a highly gifted composer and producer. He was kind and responsive, yet no one knew this. He hid his true nature behind a mask of indifference, thereby pushing people away. The cause of such behavior was a horrific car crash in which his beloved girlfriend died. After this incident, Hyun-uk's life turned into a living hell. That was until Se-na burst into his life at breakneck speed. As it turned out, this girl was the sister of Hyun-uk's late girlfriend. By a fortunate turn of events, Se-na came to Seoul to become a popular composer, and it was Hyun-uk who offered to help her achieve it. Thanks to this meeting, a spark ignited between them, and the music turned that spark into a healing flame of love.
