I Shall Master This Family (Kim, Roah)

The Lombardis were the most powerful family that ever existed in the empire. With unimaginable wealth, they shaped history, culture, and the arts—their influence rivaling that of the emperor. However, the family collapsed after making an alliance with the first prince, which resulted in futility as the second-born Perez Brivachali Durelli was crowned instead.

A Korean woman is reincarnated as Firentia, the daughter of a Lombardi and a commoner. Despite her status as an illegitimate child, her father and grandfather love her, and she works hard to keep her family's prestige intact. After the two pass away, Firentia is kicked out and has since regretted how her relatives have torn the Lombardi name to shreds.

On the verge of dying due to a carriage accident, Firentia is mysteriously given another chance in life and wakes up as her seven-year-old self. Firentia will not waste this opportunity, and if she wants to save her father and prevent the Lombardi's fall, she must prove to her grandfather her merit to become the next head of the family.
