King of Ambition

Ha Ryu is a prosecutor in charge of a corruption scandal of the first lady, Joo Da Hae. He's an orphan, and he wasn't living such a decent life in the past. But he had Da Hae by his side, and they were a happy family, including their daughter Eun Byeol. Da Hae also had rough times when she couldn't even afford her mother's funeral. Because of the painful memory from the old days, she gets ambitious for the upper crust, eventually marrying Baek Do Hoon of Baekhak Group. As Da Hae awakens her ambition to join the high class, she betrays Ha Ryu, making him fall into the bottomless pit. He starts his new life as his twin brother Cha Jae Woong and gets down to his revenge on Da Hae.
