Liu Ye, a post-80s girl with a golden collar, is a standard "leftover girl" in her late 30s. She accidentally falls in love with Lei Lei, a Phoenix man who is five years younger than her, and starts talking about marriage. After getting married, the only daughter Liu Ye found that she not only had to live with her father-in-law and mother-in-law, but also had to face many challenges brought by her husband's sisters and three sisters-in-law: finding a decent job for her sister-in-law, helping her sister-in-law deal with the "mistress", providing a "shelter" for the divorced second sister-in-law, mother and son, being constantly "harassed" by the eldest sister-in-law who hopes to have a successful son. After giving birth to her daughter Xiaoxi, her mother-in-law who favors sons over daughters continues to embarrass Liu Ye... After several years of marriage and bumps and bruises, Liuye finally used her wisdom to overcome the hardships of life, and transformed from a "golden leftover warrior" to a "model good wife" because she understood that to love someone, you must accept his whole family. It is not that difficult for a family to live harmoniously under the same roof. All it takes is a little love, a little wisdom and a little understanding.
