The merger

"After years of being together, Joan was cheated on by boyfriend with her step sister because she's the love of your parents and the inheritor of family business. Worse, she forced to marry a bankrupt billionaire's son, in her stepsister's place. In desperate need of a big sum of money to pay her medical bills for a sickness which no one knew about, she agreed. But nobody knows that the ruthless billionaire's son whom everyone despises has his own business and his own empire. Her now ex-boyfriend regrets it and wants her back? Never. Her family all beg for her forgiveness so the family business can be saved? She is ready to show the how RUTHLESS she can be."
