Data analyst Lin Siyan, an urban pragmatic young woman who believes in "cost-effectiveness" and "logic first", married love and also "married" a "couture" mother-in-law who lives in the clouds - Ms. Su Wanqin.
Ms. Su does not use ordinary water for cooking, it must be designated water from the Alps; she does not sleep on ordinary sheets, only Egyptian long-staple cotton handmade fabrics; she believes that instant coffee is "industrial wastewater", and hand-brewed coffee beans must be produced from a single estate in Gesha Village. When this "life artist" who is as refined as his hair parachuted into the small home of Lin Siyan and her husband Gu Jiaming in the name of "saving your rough life", a war about the "style" of life began.
From the placement of the toilet to the prenatal music for the child, from the material of the couple's pajamas to the family's financial planning, Lin Siyan's logical world was bombarded by her mother-in-law's "pseudo-refinement". Husband Gu Jiaming has become the most difficult "sandwich biscuit" in history, jumping repeatedly between his mother's "artistic influence" and his wife's "sobriety in the world".
