Kim Je-Ha (Ji Chang-Wook) is former solider for hire. He is also called K2. He is hired as a bodyguard by Choi Yoo-Jin (Im Yoon-A). Choi Yoo-Jin is the wife of a presidential candidate (Cho Seong-Ha) and the daughter from a chaebol family. Meanwhile, Ko An-Na (Yoona) is the secret daughter of the presidential hopeful. She is also a recluse.

It's 1997 and Kim Hyung Joon owns a small cosmetics company with a couple of friends, but the difficult economy complicates the new business and he becomes heavily indebted. With loan sharks after him, Hyung Joon decides that the only way to save the company is by launching their latest product, an innovative foundation cream. To insure its success, they decide to sponsor a contestant for the beauty pageant 'Miss Korea', hoping that she'll win and that will help promote the product at large. For that, they need to find a beautiful woman willing to go into the pageant with newcomers like them, so Hyung Joon turns to Oh Ji Young, his high school sweet heart who he broke up 10 years before, and not in the best of terms at that. Ji Young isn't very happy to see him again, but her own dissatisfaction with her job and her life make her reconsider. Written by Dama del Puente
