Becoming a Wicked Witch With a Paladin’s First Night

I was hit by a truck and transported to the world of a novel I had read. Unfortunately, I was possessed by Elenia Alfin, the evil woman from the novel, and the story begins with me sleeping in the same bed as the most loyal holy knight, Sir Rolento, if you know what I mean…
I remembered from the novel, “If a holy knight has a relationship with a woman, he is stripped of his status as a holy knight,” so I decided to try to avoid it and pretend that nothing had happened between the two of us.
Then, Rolento said something shocking: “Please, take responsibility for stealing my virginity.”
