Tsuihousareta Akuyaku Reijou wa Danzai wo Mankitsusuru

I have memories of my previous life, when I was a Japanese girl who was addicted to otome games.

Deanna is a villainess who was condemned by the prince at her graduation party, stripped of her title, and exiled to a brothel. She has memories of this game from her previous life, so she knew all this was going to happen. So before she was condemned, she bought the brothel and became its owner. She easily accepts her banishment and tries to live a happy life in the brothel, but Alexis, a close associate of the prince, comes after her....... Is he friend or foe? The retribution of an outcast villainess with no simple answers begins now!
