The Reborn Witch Raises A Templar summary:
One day, she finds herself reborn as Nielce Glory, the main character in a revenge novel and the strongest witch around—a title she earned by single-handedly taking down the Church. Despite being determined to leave all her grudges behind and face the miserable life she's supposed to have, she ends up saving Harvil, the templar who's fated to kill her later on in the novel. What was a brief moment of softheartedness has now become a major lifelong headache. And why is the usually cold-hearted Harvil from the novel acting so clingy now?
