Thirty-year-old Gu Mingyue is a full-time housewife, and her life is in trouble. The house is as chaotic as a doghouse, her husband Lu Chen is as busy as a missing person, her mother-in-law is picky and mean, and her son Xiaobao is rebellious and unruly. Just when she was on the verge of collapse, a golden finger who claimed to be the "Almighty Housewife Development System" fell from the sky. I thought it was salvation, but unexpectedly it turned out to be a "devil coach"! "Ding! Mission failed, cooking level -1!" "Warning! Insufficient mental strength, advanced skills are locked!" Gu Mingyue cried: "I finally learned how to stir-fry vegetables!" From a novice in cooking to a master of cooking, from a waste at home to a master of cooking, from a parenting madman to an expert, from a negative emotional intelligence to a prosperous person... Under the systematic "devil training", Gu Mingyue complained all the way and counterattacked. The mother-in-law changed from the initial accuser of "family crisis creation machine" to the praiser of "virtuous and capable"; the estranged husband began to look at her with admiration and took the initiative to participate in family affairs; the rebellious son also became dependent on the sensible. Just when Gu Mingyue thought she was an "all-round housewife" both internally and externally, in control of everything, a sudden external crisis pushed her to a broader social stage. It turns out that the real challenge has just begun!
