Gu Kai returns home from a business trip to find his fully paid wedding home forcibly occupied by Lin's mother and her son, the door lock fingerprint changed, and his wife condoning her maiden family's blood-sucking, forcing him to stay in a hotel. Lin's mother demands thirty thousand in living expenses, smashes the house, spreads rumors of domestic violence, and even threatens him with a knife, forcing Gu Kai to surrender the house and divorce. Gu Kai secretly gathers evidence and sues. The court rules that Lin's mother and others' illegal occupation requires them to compensate four hundred and fifty thousand, the wife leaves with zero assets due to asset transfer, and Lin's mother's family is ultimately subjected to compulsory enforcement. Gu Kai finally gets promoted and makes a counter-attack, cutting off rotten people and rotten things, facing the sun and living.
