Being the only son of a billionaire couple, Yang Seungho enjoyed all the spoils he wanted: money, gadgets, cars, girls..name it. He's worst than your typical brat, and was known to be conceited and selfish. Good thing he had childhood friends who are willing to put up with his show and to help him survive his way through adulthood – GO, Sanghyun, Joon and Mir.

He was enjoying messing up his life, until he met Soyeon. Soyeon is a police trainee who helped Seungho when he almost got robbed on his way to his car one night. Because it was his first time to see such a courageous woman with fighting skills and grace like Angelina Jolie, he fell for her that instant. Unfortunately, Seungho's reputation among the girls is something not unheard of, and so Soyeon didn't like him. But Seungho persisted, asking his friends' help to convince her that he has a good side to him. But knowing that his being a gentleman wouldn't hide his being a casanova, his conceitedness, and his punitive treatment of others, Soyeon refused to date him. Being the brat that he is who always gets what he wants, he didn't give up on Soyeon, until they became friends eventually. 

One day, Seungho's parents died in a mysterious car crash, making him an orphan at the age of 25. He became devastated, but kept himself together for he knows he had to take over his parents business. Little did he know that his father's younger brother, his uncle, plotted the death of his parents to get possession of the Yang family's riches. And because Seungho is still alive, his uncle is now planning to get rid of him so he can finally have everything...
