[Farming + gourmet food and business + transmigration into a book + reborn foil + widowed sister-in-law and younger brother-in-law + imperial examinations]
Lin Su transmigrates into a book, only for her husband to die in an accident on their wedding night.
To avoid the fate written in the book, where rumors drive her to jump into a river and end her life, Lin Su decides to take in her younger brother-in-law, whose studies will cost a fortune.
The family is dirt poor, but that is no problem. She has her family's ancestral cooking skills!
Making a fortune is a piece of cake, and becoming the richest person in the land is certainly within reach.
But before she can become the richest, her younger brother-in-law becomes chief grand secretary!
It turns out he isn't the male lead from the book, but a reborn cannon-fodder foil...
More alarming still, her younger brother-in-law seems to have fallen for her?
