Her father can't wait to get rid of her, his wife and their daughter daughter too.The man she's supposed to marry can't stand her and looks for ways to end their engagement, all to no avail.But on the day she's to get married, she finds out she's pregnant.Her fiancé finally uses the opportunity to break off his engagement to her and her father sends her packing to her aunt in another city never to return after she refuses to remove the baby like he asked her to.Seven years later, she returns to the city to claim her position as the heiress of her mother's fortune, which her father and his wife and daughter has been living off of all these years.But not as the overweight duckling everyone expected, but as a stunning, glamorous woman.Behind her are three children: a daughter who looks exactly like her, a handsome son, and another handsome son who looks too much like the most powerful man in the city.Unexpectedly, the dimwit, her fiancé who broke off their engagement comes begging for them to get married like they were supposed to.“So what if you're stunning now and lost all that weight? Everyone knows you used to be an ugly duckling. Who knows the underhanded ways you resorted to to lose weight. Forget our past and marry me again.”The woman looked at him and snickered. “Aren't you the heir of the Baker family? Why would you marry a fatso like me?”The man huffed and said arrogantly. “Hmph! Do whatever you want. But I assure you that no one in Silicon Valley will want to marry a woman saddled with bastard children!”The triplets came up on his face and snorted in disdain. “Who's this? Where is daddy when a man like this harasses mommy?”“I told you he wasn’t worth her. Hurry up and call him quickly.”The man who was in the middle of a conference call ended it as soon as he heard the news and went straight to where she was.“Are you hitting on my wife? Bastards? Are you calling the beloved children of Jett Adler bastards?”“Eh-what? Jett Adler? The most powerful man in the city? How is that even possible!”

Li Ke Lin (also Li Colin), a Chinese office worker, woke up to find himself suddenly no longer Li Ke Lin but instead Colin Lee, son of multi-billionaire in America. Having taken over the body of Colin Lee and carefully imitated his manners and bearings, his next goal is to inherit his father’s wealth. However, when his father lists the condition of marrying a woman who feels repulsed by Colin Lee’s (not Li Colin’s) dalliances, and whose very nature is the complete opposite of Colin Lee (not Li Colin), what must he do to gain her affection?!
