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 met 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 in the footsteps of his estranged father, but an incident caused him to quit law school and become a singer-actor.
The two later reunite when Noh Eul is tasked to film Shin Joon-young's documentary. She convinces the producer that she can obtain his consent for the documentary shoot. Initially, Joon-young gives Noh Eul a hard time, but he eventually agrees to participate in the documentary. As they work together, he endeavors to mend their relationship and win her heart back.
