As Yang Li Wei went through the lowest point of his life, he met a fortune teller, Chen Shun Tian. Under Shun Tian's guidance, he picked himself up and became a successful financial investment manager. However, just as he thought things were going well for him, an investment mistake costed him his wealth and sent him into debts. Met with a dead end, he intended to take his own life on the ferry, only to meet someone that looked exactly like himself.

Upon surviving an unfortunate accident on the ferry, Li Wei decides to feign amnesia and impersonate Rui Ming to escape from his financial difficulties. As Rui Ming's wife brings him home, Li Wei meets Rui Ming's children and brother, Zi Jian, Jia Wen and Rui Jie. With an interest in inventing new gadgets, Zi Jian gets Li Wei to trial his new invention, a lie-detecting watch, where Li Wei's true identity is almost leaked

Just as he thought Rui Ming's identity would grant him wealth for life, Li Wei discovered Rui Ming's involvement in embezzlement activities. Not only did Rui Jie not offer a helping hand, but also plotted several attempts to take over Rui Ming's status and power. As Rui Ming's mistress, Monica, continued to pester him, Li Wei tried to keep a distance in fear of revealing his identity, causing Monica to explode with anger

Rui Jie brought Li Wei to the Home where their father, Jian Ting was admitted for dementia. Much to their surprise, Jian Ting could only recognize Li Wei as his son, and happily let out to him on where he kept his "money". Assuming that Jian Ting was referring to the embezzled funds, Li Wei quickly went to retrieve the "money", only to find out that they were just play money.

Not being able to tolerate Rui Ming's repeated betrayal of their marriage previously, Si Ting sent a killer to murder Rui Ming under the influence of alcohol. However, when the killer took action and injured "Rui Ming" (Li Wei), Si Ting felt overwhelmed with guilt and opened up to him on the truth. Much to her surprise, not only did Li Wei not blame her, but also bore the responsibility on his part. The relationship between the couple then turned for the better.
