Yu Xiaojiao (played by Fu Yiwei) and Qiu Jiabao (played by Lu Liang) got married, the relationship between mother-in-law and daughter-in-law is already complicated, and Qiu Jiabao is the second marriage this time, and their family relationship is even more troublesome. Qiu Jiabao's mother (played by Zheng Yuzhi) is very self-assured, and she always has a lot of unpleasant things about her new daughter-in-law, and she competes with Yu Xiaojiao openly and secretly. Qiu Jiabao also has a younger sister, Qiu Jiazhu (played by Yang Kun), although she is not young, she is still unmarried, and often joins this mother-in-law and daughter-in-law war, which intensifies the conflict. This time, not only did Xiaojiao complain bitterly in her heart, but after a long time, her husband Qiu Jiabao was also helpless because of splint anger. On the other hand, Qiu Jiabao often has dealings with his ex-wife and daughter, and in an already discordant family environment, Yu Xiaojiao often hates her husband because of this. Who will be the final winner in the mother-in-law and daughter-in-law battle? How does Qiu Jiabao weigh the multiple identities of husband, son, brother, ex-husband, and father?
