Synopsis : Woo Hyun (Park Yoo-Hwan) is the leader and most popular member of idol boy band m2. He acts like a sweet person, but he is actually mean and arrogant.

Seung-Yeon (Ko Eun-Ah) plays classic piano at a music school in England. Because Seung-Yeon decided to play Beethoven in her own way, the school kicked her out. On her flight back to Korea, Seung-Yeon vomits on Woo Hyun, who is returning to Korea after a concert in England.

Back in Seoul, Seung-Yeon stays at Ji-Woo's (Kwak Yong-Hwan) house and does not tell her parents that she is back. Seung-Yeon and Ji-Woo are best friends. Ji-Woo is a trainee at Sunny Management Company.

Sunny Management decides to overhaul boy band m2 with new members. The present members will be "graduated," but fans of m2 oppose the idea and demonstrate outside of Sunny Management's office. Sunny Management holds an audition, which Ji-Woo takes part in. Due to being nervous, Ji-Woo fails his audition. His audition video is posted on the internet. This riles up fans of m2 even more, complaining how the applicants are worse. Hyun-Seok (Hong Kyung-Min), president of Sunny Management, holds a press conference and announces that they will pick new members of m2 through fan voting. A survival audition is then held.
