My Lady Master (DaraGon)

Park Sandara is a Campus Sweetheart during the day and a Badass B*tch during the night. She is the only daughter of the CEOs of PRK Enterprise. But unknown to the public, they also own an underground arena where different kinds of gangsters are fighting for money (and fame probably). Although her parents are busy, different in most stories of a rich kid, they always make sure to spend some time with their daughter.

Meanwhile, Kwon Jiyong is a typical gangster. He has a life which normal gangters have. His mother is already gone because of a car accident (or he thought it was) and his father already abandoned them, him and his sister Hayi. They were saved by the CEO of PRK Enterprise when the company was looking for aspiring business men to attend a training. He spent all of their savings so that they can attend it. He have his full gratefulness to the Parks. He respects them.

But what will happen if the path of a man and the daughter of his savior met? Will they have a friendly start which eventually end in a love type of relationship or not? Is it a good thing because they met or a bad thing because they met?
