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?
