44-year-old chemistry teacher Xue E and her husband Kang Laoliu, who became obsessed with shooting short dramas after being demobilized, fall into a speech-and-sexless silent marriage and resolve to get a divorce. Kang Laoliu's younger sister Kang Pei runs a small restaurant, is a romantic fool, and is ignored and PUA'd by her live-in husband Ji Long. 26-year-old Lian Yijia has deep rifts with her delivery driver boyfriend Ma Haoran. Ma Haoran dies in a car accident, and she accidentally gets pregnant, making an agreement with her father-in-law Ma Baocheng to leave once the child is born. Retired railway worker Ma Baocheng, who lost both son and spouse, relies on Qinqiang opera to dispel his grief. Xue E is attracted by Ma Baocheng's Qinqiang singing and gets acquainted with him, and subsequently Kang Pei also joins, with several of them forming a Qinqiang amateur music class. They break free from the internal friction of marriage and no longer force partners and perfection.
