Lin Xubai believed he had a happy family until he accidentally discovered that his marriage was actually an elaborate, carefully orchestrated scam. His wife, Jiang Yubing, conspired with an outsider to set him up, using the excuse of helping her best friend care for a child to conceal their affair, while also plotting to seize his company's shares. For three months, he endured the humiliation and secretly gathered surveillance footage, paternity test results, and financial transaction records, while suffering the misunderstandings and accusations of friends and family. When he finally exposes the entire conspiracy in front of everyone, he puts an end to his sham marriage. Despite the pain he has endured, he still chooses to treat the innocent child with kindness, uses the law to defend his rights, leaves his broken past behind, and embraces a new beginning.
