Xiao Yihang and Zhuang Min are a loving couple. Xiao Yihang is the president of a leading logistics company, while Zhuang Min is a top TV show host. They have a daughter named Pong Pong, and their family is very happy and content.
However, misfortune struck unexpectedly. Zhuang Min received a blackmail call from Ma Pingyuan, her high school teacher who had raped her back then. Zhuang Min, unyielding and unwilling to give in, fought against the deranged Ma Pingyuan but at the same time did not want her husband to know, thus enduring immense inner torment.
Zhuang Min's abnormal behavior made Xiao Yihang suspicious. He secretly followed his wife and eventually uncovered everything. The demon from the past, Ma Pingyuan, was now the vice president of a debt transfer company and had business dealings with Xiao Yihang.
Xiao Yihang was furious. He arranged a meeting with Ma Pingyuan, intending to resolve the matter between the two men. Ma Pingyuan readily agreed.
Soon after, Ma Pingyuan fell to his death from a building. Upon learning that Xiao Yihang had known about this all along, Zhuang Min became suspicious and questioned her husband about his whereabouts on the night of Ma Pingyuan's death. Xiao Yihang told his wife that Ma Pingyuan deserved to die.
As time passed, life seemed to return to its former tranquility, but no one expected that a bigger conspiracy was brewing...
