Reincarnated as a Villainess Into an Adult Dating SIM and I Want to End Up With My Bashful Fiancé

Villainous noble girls? Routes? I don’t know anything about games or anime, but for some reason I was reincarnated into the world of an 18+ otome game!? I was an ordinary office lady, but after an accident, I was reincarnated and lived as the daughter of a marquis, Foria, while keeping the memories of my previous life alive. One day, the heroine Maria, who was also reincarnated, told me that if I continued as per the game's scenario, I would be destroyed...?! In order to avoid being condemned, the only choice I had was to win the heart of my fiancée, Al!! I didn't want to die, so I have let myself be captured (R-18) by my tsundere handsome childhood friend?!
