Yoo Ah In returns to the small screen for the first time since, Sungkyunkwan Scandal in SBS's newest hit, Fashion King. Joining him is the increasingly popular, Shin Se Kyung (Tree With Deep Roots) and Lee Je Hoon (Three Sisters). Rounding out the cast is Kwon Yuri of the ever-popular Korean Pop group, Girls' Generation in her acting debut. Fashion King tells the story of Lee Ga Young (Shin Se Kyung) who is a talented seamstress that is driven out of her foster home after being falsely accused of arson. Kang Young Gul (Yoo Ah In) owns a small-time clothing store that reproduces faux designer clothing. When Young Gul's former classmate and successful fashion entrepreneur, Jung Jae Hyuk (Lee Je Hoon) refuses to give him a loan, Young Gul swears to one day buy his company out. However, Jae Hyuk is more concerned about getting back together with his equally successful ex-girlfriend, Choi Anna (Kwon Yuri). Through a series of events, these four meet once again on the other side of the world in New York City. The fateful ties of these aspiring designers are triple-knotted in a story about new challenges, rivalry, success and love.
