Help

I'm totally blanking, can someone help... I read this manhwa it was about a girl reincarnating into the body of a hairy beast woman (who was originally a super pretty girl) then the girl who reincarnated was like I have this handy dandy thing called waxing and she had like a glow up, and her sister was like oh shit she's back because the sister was courting the husband. OOh, and the mc was brown and there was a monster duke with black hair black eyes.
