My Fiancée is a Reincarnator and Apparently a Villainous Noble Lady

My fiancée suddenly said something like, "I have memories from my previous life. This is the world of an otome game. You are a capture target, and I am the villainess character who gets in the way of the heroine." I don't understand what she's talking about. Is she okay? While my fiancée becomes increasingly demanding, I find healing in an angelic female student. ※Main story: 5 episodes complete + several bonus episodes. ※I have no experience playing otome games, so please enjoy this based on the atmosphere and tone.
