Modern elite Qiao Ran and wealthy heiress Xia Xiaoqi accidentally travel through time to Gegeshi Village in 1978, becoming sisters-in-law in the Lu family. In the original book, they were tragic supporting female characters: Qiao Ran would drown herself in the river due to infidelity, and Xia Xiaoqi would be sold and fall off a cliff. But the two refuse to accept their fate, joining hands to confront the harsh mother-in-law Liu Chunhua and the scheming sister-in-law Lu Hongli, and cleverly defusing the calculations of scumbags like Cheng Fangyuan. In the process, they respectively attract the gentle Lu Xiangnan and the cold-exterior-warm-interior Lu Yanbei, and even drive the mother-in-law to change, ultimately rewriting their destinies, harvesting love and family affection, and starting a happy new life.
