A clear-headed, unhinged female lead who is reborn after being worked to death by her mother-in-law in the 1980s, paired with a vicious, insufferable mother-in-law. After being reborn, they swap identities. Reborn memories + a group-buying System + a two-way identity swap.
In her previous life, the female lead was a tough young wife in the 1980s, exploited by her awful mother-in-law and betrayed by her scumbag husband, until she was finally worked to death. She is reborn carrying boundless resentment. By coincidence, her awful mother-in-law is also reborn after an accident. The instant they are reborn, their identities swap both ways: the female lead takes on her mother-in-law’s identity, with control of the family finances and a say in household matters, while the mother-in-law takes on the female lead’s identity, exploited by the whole family and forced to live under someone else’s roof.
Using her memories from being reborn and her group-buying System, the female lead uses her mother-in-law’s identity to “set the household straight”: she cuts off the money flowing to her mother-in-law’s family, forces her scumbag husband to get his act together, and teaches her outrageous sister-in-law a lesson. At the same time, she uses the System to run a group-buying side business, reselling scarce goods from the 1980s, and makes a fortune. Wearing the female lead’s identity, the mother-in-law experiences firsthand the same cruel exploitation she inflicted in her previous life: the neighbors gossip about her, her scumbag husband treats her coldly, her own family looks down on her, and she has to deal with the female lead’s counterattacks. Her arrogance soon gives way to utter misery.
While using her mother-in-law’s identity to build up capital and collect evidence of her husband’s and mother-in-law’s past misdeeds, the female lead takes advantage of their swapped identities to make the mother-in-law witness her own cruelty. Once they finally switch back, she publicly tears into her scumbag husband and awful mother-in-law, divorces him to cut her losses, and uses her System and wealth to make a comeback as a successful businesswoman in the 1980s!
