- Description from zhuishubox (translated)

In her last life, Qu Zhi tried her best to be a good wife who was sensible and did not cause trouble, a filial and good daughter who helped her family, and a good mother who accompanied her children. However, Qu Zhi worked hard and suffered all her life. When she was about to die, she realized that in the end, all she got back for her hard work were complaints. Her husband complained that she was an idle, rich wife all day long who wasn’t satisfied with her happiness at home, and that she was a greedy woman.

She had spent her whole life as a loner, and she had nothing. Lying on the operation table, Qu Zhi thought that if she could do it all over again, she wouldn’t be a housewife. She wouldn’t have given her second daughter away, and she wouldn’t take care of her blood-sucking relatives.

She wouldn’t marry her indifferent, cold husband either! When she next opened her eyes, she was back to twenty years in the past. Her eldest daughter was still in elementary school, and her second daughter had been in her belly for several months…
