House Garnet's Archvillain

Estelle, the empire's saint, was an illegitimate child who tried her best to be loved by her family and fiancé... until they sacrificed her to a demon for the sake of their greed. After 600 years of being tortured, she makes a deal with the demon to return by possessing the body of Jewel de Garnet, the only child of a powerful noble family. With her new identity and fierce determination, will Estelle successfully carry out her revenge? Or will someone from her past stop her from doing so?
