The Young Lady Who Manipulates Fate (Daughter C Remake Version)

I was deeply into the otome game "Land of Witches," and when I realized it, I had been reincarnated into that game world. With this great opportunity I was supposed to save my favorite last boss Duke from the bad ending in this lap... But wait a minute! The scenario is completely different from my memory! Or rather, I was reincarnated as the Duke's... "daughter"?
