I Possessed the Final Villain of the Horror Game

I entered a horror game. Not even as the main character, but as the final boss! The narrative states that she will die from fear after seeing a ghost with a terrible appearance. But then again, if she doesn’t do the rituals written here every time the Crimson Moon rises, she will die a horrendous death. “Why are you trying to run away? You went to bed in my arms before…” “Use me to your heart’s content and command me. I was born to be your sl*ve.” “That’s why you should have protected yourself a little more so I wouldn’t be interested in you.” It’s already hard enough to survive, but why are the characters that were supposed to be supporting roles approaching me?! I don’t think these guys are normal either…
