Lin Yanqiu, an associate professor of nutrition, was testing a milk tea recipe with her student Gu Siyao in the lab when an explosion occurred. When she opened her eyes, she'd become the “abused stepmother” of the wealthy Gu family. The original owner was timid and easily bullied, while her daughter Gu Siyao had been reborn with memories of her previous life. This former teacher-and-student pair, now mother and daughter, had barely arrived when they ran into a plot involving poisoned soup concocted by her stepsister Lin Wanting. They also discovered that Gu Mingzhe, the Gu family's illegitimate son, was working with a collateral branch to hollow out the main household's business with inferior ingredients!
The Gu family had strict rules: “Keep family scandals in the family” enabled corruption, while “blood comes first” put parasites in power. They were also bound by shared interests to wealthy families such as the Shens and Lus, where one wrong move could affect everything. Armed with her “Teacher-Student Milk Tea Development Journal,” Lin Yanqiu used professional testing methods to expose the poisoned soup and the conspiracy involving substandard ingredients, gradually taking control of the supply chain. But then Gu Mingzhe and the collateral branch joined forces to withhold rents and incite the Shen family to cut off supplies. Gu Meilin's mother used public-interest causes to manipulate public opinion, setting off a business crisis involving halted real estate projects, canceled private banquets, and creditors surrounding the gates. The Gu family fell from the clouds into the mire.
Facing the constraints of wealthy-family rules and attacks from all sides by evil forces, Lin Yanqiu pawned her jewelry to cover the debts, broke the public-opinion crisis with transparent charity work through her milk tea business, and resolved misunderstandings between social circles with customized milk tea. In the midst of the crisis, she also roused her husband Gu Jingchen and warmed the heart of her stepson Gu Sichen. In the end, she not only rooted out every parasite but abolished the old rules and established a “Milk Tea Council,” transforming the Gu family from a web of mutual interests into a community built on trust.
As it turned out, “taking down a wealthy family” simply meant using cup after cup of clean, transparent milk tea to protect the warm, peaceful daily life of a family together.
