Chen Yuan and his wife Li Yue have been living a DINK life for fifty years, thinking that they would die in peace. Before his wife died, a "secret family member" appeared, which not only allowed Chen Yuan to leave the house, but also revealed a lie that had been concealed for half a century. In despair, Chen Yuan accidentally inherited his mother's huge inheritance and regained his confidence in life. As the private detective's investigation deepened, it emerged that the deceased wife had transferred assets during her lifetime and that her ex-lover had faked her death.
