Kim Min Hee

Hwang Ji An is a successful shoe designer whose life revolves around her work. She's fiercely protective of her designs, though they are constantly being copied, flooding the market with cheap knock-offs. Park Tae Kang is a young, talented designer, but still regularly rips off Ji An's designs for the easy money. A particularly bad day for the both of them brings them together over drinks, leading to a one-night stand. They swear never to see each other again, but things get complicated when her company hires Tae Kang as a new employee, and Ji An discovers that she's pregnant with his child!

When brash, street-smart orphan Oh Dae San, who makes his living copying designer fashions, and the apathetic grandson of the fashion empire Lee Joon Hee meet by chance one day, the two men realize that they look exactly alike and in that, they see a chance to set each other free. Pressured by his stepbrother and stepmother to give up his rights to his grandmother's business, Joon Hee wants to investigate his family background in secret, so he decides to hire Dae San to distract attention for a day. Dae San, initially resistant to the idea, has become involved in the financial difficulties of the daughter of a recently-deceased friend and will do anything to help her. What starts out as a one-day deal turns into something deeper and more complicated, as secrets arise about the real connection between them.
