Shin Joon-young (Kim Woo-bin) and Noh Eul (Bae Suzy) were classmates who were separated during their teenage years due to an ill-fated relationship, but later meet each other in adulthood. Shin Joon-young is now a top actor-singer while Noh Eul is a documentary producer.
Noh Eul had a tough childhood; her father died in a hit-and-run prompting Noh Eul to quit school and make a living for herself and her brother. Shin Joon-young, on the other hand, had his life planned out for him. His mother wanted him to become a prosecutor to follow the footsteps of his estranged father, but an awful incident caused him to quit law school and become a singer-actor. The two reunite when Noh Eul is tasked to film Shin Joon-young’s documentary. Joon-young initially gives Noh Eul a miserable time before finally agreeing to do the documentary and even plans to win her heart back.
