Jeong-woo will do anything to win favor with the President’s family, unfortunately, the woman Tae Kyuk loves turns out to be Jeong-woo’s first love. Soo Hyuk, who doesn’t remember Jeong-woo, finds herself gradually drawn to him as he pursues her under his master’s name.
After learning the devastating truth of his father’s true identity, Jeong-woo is set on a whirlwind of a quest involving crime, love and revenge, taking him from the glittering lights of Vegas to the diamond mines of Africa.
