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.

But after decades of marriage, her husband had a firm, deadly hold on all her money, and she didn’t even have a dime to her name, nor a property to call her own. Every time she asked for money, he would trample all over her self-esteem. Her husband’s cold and sarcastic words made her unable to lift her head, and his friends would demean her while drinking wine, making her tremble with anger. This man had once said he would take care of her, yet he turned a blind eye! Those people focused on her happiness as a topic, and made a joke out of it.

Even her three children resented her for her uneven love towards everyone, and their relationship only became more strained as time passed. 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…
