I'll Be the Matriarch in This Life

Florentia is reborn as the illegitimate child of the empire’s wealthiest family, and for a while, it seems her future is set. But after her father dies, her relatives cast her out, and the once-great family collapses—until one drunken accident sends her back to the age of seven. This time, with the cold second prince who was once her family’s enemy now following her around like a loyal puppy, Florentia is determined to claim both him and the family for herself.
