S-Rank Throne: Princess Ascends

Lillian wakes up inside a novel as the useless Fifth Princess of the Elven Kingdom, a character who is doomed to die in the first episode as a blood sacrifice to a vampire. Her accidental awakening of a sealed S-rank vampire gives her a single wish, and she uses it to demand that he follow her for the rest of her life. Knowing that her rival Lilia will try again if left alone, Lillian begins seizing whatever was meant for her sister, from a werewolf companion to the queen-candidate spot. The stakes rise as Lilia's hatred grows and her desperate final act threatens the whole kingdom.
