The SSS rank Villain is captured by Yandere heroine

Wait… What?! I reincarnated into an erotic game! Where is my damn golden finger!? Kylian von Hansen wakes up in the body of the fiancé of the heroine of an erotic otome game. His mission? Change the scenario to prevent the destruction of the world. With mediocre talent and no cheating, he fails miserably at preventing the Villainesses from turning to the dark side. But why are all these Villainesses trying to kidnap him one after another? Since when do these ridiculous rumors circulate, claiming that he cheated on his fiancée with the Vessel of the Primordial Darkness? Kylian doesn't know it yet… but his ex has reincarnated into the body of the Saintess… and the five Villainesses and the heroine each possess their own cheat that gives them absurd and dangerous quests centered on him. [Yandere System activated] [Quest: Kidnap the princess's fiancé: Kylian von Hansen!] Trapped between his yandere fiancée and ultra-possessive villainesses, Kylian quickly understands one thing… If he doesn't regain control and find out who is pulling the strings of these systems… he will end up dying, or worse: becoming The Fool, the leader of the cult that worships the primordial goddesses.
