It is a split-official drama, with the female protagonist Cai Nana (Oh Ji-won) and the male protagonist Seo Jung-hou.
He is a futuristic professional runner of the 22nd century with beast-like intuition and extraordinary martial arts prowess. He leaves no trace when doing things and can complete any task perfectly as soon as money comes. He is the sexiest and most mysterious errand boy in the industry. His dream is to save money to buy an island in the South Pacific and live alone.
But after he met her, his life changed drastically.
