REVENGE IS AN EXPENSIVE BUSINESS.

Even after making billions of won in real estate ventures, Hyeonwoo-reborn as Dojun, youngest grandson of the powerful Soonyang Group-still needs more money to take down the ruthless corporation behind his murder. He enlists the aid of Sehyeon Oh, president of an asset management firm. But as the two start working together, Sehyeon begins to suspect that twelve-year-old Dojun is not quite what he appears to be.

Meanwhile, Dojun's grandfather is shocked to discover where Dojun invested his money-in the film industry, the very sector that got Dojun's father ostracized by the Royal Family! Will his grandfather step in to cut off Dojun's schemes and thwart his dreams of revenge?
