On the seventh year of her marriage, stay-at-home mother Lin Wanqing accidentally discovered that her husband Shen Mingchuan had cheated on her with company secretary Su Xue. When she questioned her with conclusive evidence, Shen Mingchuan not only showed no guilt, but also forced her to leave the house on the grounds that "I earned every penny you spent." In order to fight for the custody of her daughter Tangtang, Lin Wanqing resolutely signed a divorce agreement and moved her five-year-old daughter to the villa she had rented for many years, starting the difficult journey of survival for a single mother.
