Ko, Konna Ikemen ga Watashi no Osananajimi de Konyakusha desu tte?

Before she knew it, Rin suddenly finds herself reborn as Richelie, the daughter of a duke from a country called Eirland. Her fiancé is the crown prince, Zenon... Could this really be the world of the otome game her little sisters are crazy about? And what's more, she's the villainess who tricks all the targets into having sex?! ...For someone with a zero love quotient, naturally this is far too difficult! Rin wants to quietly aim for the bad ending and go to a convent, but she finds herself getting sucked deeper and deeper into Zenon's swamp of suspicion... A turbulent love fantasy about the heroine, reincarnated as a villainess, who is the polar opposite of her character X her sadistic childhood friend, the crown prince.
