Kim Joo-Won (Hyun-Bin) is from a wealthy family, smart and good looking. He runs the luxurious Roel Department store, which his family owns. Oska (Yoon Sang-Hyun) is a popular singer around Asia, but he doesn't have musical talent. He is also a womanizer. Joo-Won and Oska are also cousins and highly competitive towards each other.

On a request by Oska, Joo-Won goes to pick up actress Park Chae-Rin from a shooting set. Joo-Won mistakes stunt woman Gil Ra-Im (Ha Ji-Won) for Park Chae-Rin and takes stunt woman Ra-Im to a hotel. Oska made the request in an attempt to prevent Park Chae-Rin from revealing their relationship to the press. At the hotel, Joo-Won discovers that the woman he picked is not actress Park Chae-Rim but a stunt woman. During this time, Joo-Won starts to experience strong feelings for the feisty stunt woman, even though she isn't his type. Joo-Won tried getting Ra-Im out of his mind for Ra-Im does not own a high status life nor is even rich. Nevertheless, Joo-Won can't stop thinking about Ra-Im.

Later, Joo-Won sneaks into an action school to watch Ra-Im. Meanwhile, Ra-Im tries her best to ignore Joo-Won because she knows Joo-Wan belongs to another higher social level compared to her. Nevertheless, Ra-Im can't help her blooming feelings towards Joo-Won.

Yeun-Sul (Kim Sa-Rang) and Oska are ex-lovers, but they can't seem to forget each other. Because Yeun-Sul had a high-living status, she was arranged to attend a blind date with Joo-Won. Even though Joo-Wan made it clear that he doesn't have interest in her, Yeun-Sul keeps pursuing Joo-Won. Yeun-Sul knows Joo-Wan is Oska's cousin and wants to use him to get under Oska's skin. Yeun-Sul then manages to become the director for Oska's next music video, which is scheduled to be shot on Jeju Island.
