Kyung Mi - You

You are the daughter of the president of a huge company in Korea, and you are expected to take over once your old enough. But for now you are stuck working in the office. The people in the office can't stand you, they see you as a manipulative little girl with no ambitions. Despite your great work ethic. So when a new employee comes in people start to talk. Will he turn out to be the one to take over the company, leaving you to work elsewhere? Or will you hold down your position and beat him in a race that only you have established?

Kim Jongin - Kai

The new guy at the office. The only reason he has a job there is because his father is an old friend of yours. He's cocky, and lacks ambition. So when everyone thinks he will take over instead of you he tries his best to do otherwise. He flirts with all the woman at the office and with you the most. Only because you are his partner for a big upcoming project. Will he learn what is really important for him and the company? Or will he choose to ignore everything and go after the only thing he wants?
