The Heroine, Caroline gives cookies to Rufus and the other male leads in the Otome game. Of course, Rufus, who is vigilant and wary of the heroine, never ate the cookies. Ever since MC told Rufus a "prophecy" that he will meet a cute girl with blonde hair and pink eyes named Caroline, he always wonders why would he just suddenly fall in love then abandon his fiance even though he is a family-oriented type. Also, it is not logical to suddenly annul his engagement.
He visited our MC to tell her about the cookies and that he suspected poison. So they both decided to test it out with a rat. Rufus fed the cookies to the rat and is showing symptoms of illusions, confusion, etc. The cookie was like a love potion. MC thinks the other boys who received the cookies are affected and asked Rufus to create an alibi for the girls who are going through their fiance cheating as she doesn't want them to suffer. ML accepted his precious fiancee's request.

I was theorizing that maybe the MC has a mental health problem kinda like DID/MPD (Dissociative Identity Disorder/Multiple Personality Disorder) and the roles he acted are his different personalities that have their own stories and experiences, and the story covers it up as if it was magic and he just gets transported to the world he acts in...
But I don't know since I'm not really a professional and I just came up with this instantly from the little information I already have about DID/MPD in my tiny ass brain... please don't attack me since I'm stupid and I'm just here to share theory me and my small brain came up
