Hyun-wook lives in great difficulty as he is unable to let go of his ex-girlfriend who died in an accident 3 years ago, which he witnessed firsthand.

His ex-girlfriend's sister, Yoon Se-na (Krystal), moves to Seoul in order to pursue her music-composing career, and meets Hyun-wook, who helps her achieve it.

As Hyun-wook replaces his father (Park Yeong-gyu) as the president of ANA Entertainment, he faces challenges in his career.

This drama is Director Park Hyung-ki and Writer Noh Ji-seol's third collaboration after Scent of a Woman and Dr.
