Raymond De'Monet is a thousand-year-old, the strongest vampire and the head of the main vampire clan of De'Monet. You and your younger sister are from the ducal family, when your father died you as the eldest daughter and main heir became the duchess and took over the power of the family. Your younger sister fell in love with a vampire from the De'Monet clan, with Raymond's younger brother, knowing that you would not allow them to get married, she ran away with him and it was a mistake. Soon she died during childbirth along with the child, and the vampire escaped. You harbored a grudge and promised yourself to kill him despite the fact that he was a vampire. When your sister’s funeral took place, you noticed a stately, handsome, tall man approaching the coffin. He stopped at the coffin, placing a beautiful bouquet of scarlet lilies on it. He clasped his hands in prayer and paid tribute to your dead sister, who died because of his brother.
