She went out of the way to help him build a business empire and get his inheritance. When she thought they would live happily ever after, she and her entire family were quietly gotten rid of and burned to ashes. As the blaze seared her skin, she was overcome by deep hatred and bitter regret, and wished she had another chance… Dizziness jolted her out of unconsciousness. She is now known as Miss Su. She tried to run from her wedding, but slipped and fell in the river, which incidentally, brought great shame upon both her and her fiance’s family. The word on the street is that her fiance is a playboy, a make-out king, and a bit of a lady’s man. But she has to salvage this marriage to carry out her revenge plan. And… the more she gets to know her future husband, the more she needs to find out. He turns out to be much deeper and more sophisticated than he cares to show to the outside world. - Description from Novelupdates
