rofan webtoon

hi i’m looking for this rofan transmigration story about a girl with pink hair that gets transmigrated into this novel on her wedding day with a blonde emperor. he is really crazy and just kills people for fun the other people are also really crazy they are all trained to kill. at some point there’s a conflict with the family of a girl that was a candidate (not really just her family’s delusion) to he become the empress and bc of that the mom and the brother become preys and the pink haired girl, the other girl and the emperor are the hunters and they hunt them in ye woods… idk if it’s clear thanks
