Fu Cheng, President of Fu's Medical, was drugged by someone on a plane and had a one-night stand with air hostess Fang Xinyue. However, he mistakenly identified Ye Manli, the chief stewardess, as the person involved. Out of a sense of responsibility, he arranged a position for Ye Manli in his company, but there was no substantial relationship between them in the following eight years.Unaware of Fu Cheng's identity, Fang Xinyue gave birth to their son Xiaotian alone and raised him. Five years later, Xiaotian was accidentally hit by Fu Cheng's car at a road intersection. Fu Cheng felt an inexplicable sense of familiarity with the mother and son, so he offered help and even provided Fang Xinyue with a job opportunity. As Fu Cheng spent more time with Fang Xinyue, he gradually uncovered Ye Manli's lies and also began to suspect his past connection with Fang Xinyue.
