No Way to Forgive

A thousand years after the Western Dynasty, a system exists that can bind a person to a mission and hold them to it. Isabella ruled that dynasty as empress, three palaces and six wings of a harem under her, until an assassination attempt. She wakes in the body of an illegitimate daughter of a modern family, bound to the system, and the mission is to marry the young heir of the Perry family. The grandmother is strict, the brother and sister in law are cruel, and the husband spends his time as he likes. Isabella smiles at it. She reorganises the Perrys. Her husband, the one everyone writes off, is keeping something of his own hidden.
