Woojin was a rich and powerful mafia boss in Korea. He had a sister, Eunji, she was very pretty and everyone's crush.

A guy named Dae fell in love with Eunji, but she rejected him and her father made a bet with Dae, that he would give him his son. Woojin didn't want that but he was forced to.

"Since we live together, you're gonna sleep on the couch, and i don't want any lovey Dovey things, understood?" he said in a cold tone while gazing Dae with a sharp look.
