Qin Nuan, the 18-year-old real daughter of the Qin family, was sent to a mental hospital for half a year by her eccentric brothers because she beat and bullied Qin Rou, the fake daughter. After returning, she pretended to be weak and was instructed by Dr. Qi to fight back as a "mental patient", forcing the other party to take action first. She was sleepwalking and shocked, and step by step exposed Qin Rou's nanny's evil deeds. The brothers gradually discovered the truth and felt guilty, but Qin Nuan had already been hurt by family ties. She seemed crazy with an IQ of 160, but in fact she controlled everything, made the bully pay the price, and finally drew a clear line with the cold Qin family.
