Synopsis: Sadistic Lover Grace

It is said that there is a mistress who lives in a suspicious mansion that speaks to no one and yet solves peoples' worries. "Human greed knows no limits. One must become a monster in order to not be destroyed by monsters." She binds you in her rope and then releases you, like a cocoon turning into a butterfly. It looks like there's another strange guest visiting tonight as well... I wonder who it could be this time? [Original Webtoon](https://www.comico.jp/comic/6811)
