Many years ago, a young woman named Min Hui fell for a young man named Xin Qi. They dreamed of spending the rest of their lives together and had even planned to marry. But things between them became complicated. Xin Qi suffered from a dangerous and potentially life-threatening heart condition. And a misunderstanding between them led them to split acrimoniously.

Now, years later, they are reunited at a business event. Min Hui has risen to become an R&D director at a tech firm and Xin Qi has also made a name for himself in the business world. Deciding that “fate” has brought them back into contact for a reason, they start to talk. But Min Hui reveals that she has a son. What is more, a paternity test appears to show that the child is Xin Qi’s! Xin Qi reacts by taking on the role of the boy’s father – much to the child’s delight. But will this lead them back down the path to romance? Or has their love ship already sailed?

Karnploo is an orphan that has been raised by an aunt who treats her like a servant. When her aunt wants money to continue her lavish lifestyle, she sells Karnploo to an older, wealthy man. Karnploo is unaware of her aunt's arrangement, and believes she is going there as a servant. The older man has a grown son, Nit, who misunderstands Karnploo and thinks she is his intended bride rather than his father's. He accuses Karn of selling herself and trying to cheat his family out of their fortunes. He treats her like a prostitute, even going so far as to rape her. When he discovers that Karnploo is actually his father's intended wife, he continues to mistreat her, hoping she will back out of the arrangement.
