I transmigrated into the body of the notorious marquis’s daughter—

a disgrace to the family and a walking disaster, known for nothing but her nation-treasure-level beauty.

Until the age of five, no one even looked for her. She had been abandoned in a corner of the ducal estate.

If this keeps up, we’ll both be thrown out just like in the original story—and end up dead alongside that useless father of mine.

In a hurry, I start cleaning up the messes my father caused, dealing with the women he charmed and discarded, and handling every bit of troublesome aftermath.

And after successfully managing all that chaos—

The noble and dignified grandfather summons me.

“You are far more useful than your father. Succeed me.”

“…Pardon?”

Me? All of a sudden?

This is the story of Erusha, who tries to reform her devastatingly handsome but hopelessly incompetent father—only to end up taking over the entire family.
