Chen Lili, a designer in Shanghai, bought a house with full payment before marriage as a way out. After marriage, she softened her heart and let her sister-in-law and her family live temporarily, and her mother-in-law also moved in. The family of seven lived and ate for free for three years. She became a free nanny and was repeatedly exploited. She was slapped by her brother-in-law for complaining, and her husband remained silent the whole time. Frustrated, Chen Lili quickly sold her house and filed for divorce. The new landlord came to clear out the house, and the Zhou family lived on the streets. Her husband's family spread rumors and threats, but she used evidence to expose them. In the end, she successfully divorced and won custody of her daughter. Her husband's family was deported and her husband became a delivery boy. Chen Lili started a counterattack and became a dark horse in the design world.
