I Received a Prophecy That My Fiancé Would Fall for Someone Else

I received an anonymous letter.

It included a prophecy stating that my friend, Lady Margareta, would be possessed by the soul of a “college exam repeater,” and that she would go on to steal the hearts of all the great men of the empire, creating a reverse harem.

According to that prophecy, even my fiancé, Karian, would betray me and confess his love to her…

“If you cheat on me, I’ll kill you.”

“…Are you obsessed with me right now? That’s so hot!”

But I can’t rely on this guy’s willpower alone.

It’s probably a prank, but just in case, I need to take a few precautions.

I must block the evil spirit that possessed my friend—and protect my fiancé, too.

“What is this? A consent form to forfeit physical autonomy?”

“That’s rude, Karian. It’s a Physical Autonomy Waiver Form, thank you.”

I casually brushed off a loose thread from my skirt and explained further.

“It basically says I’m allowed to restrain you or place mild limitations on your behavior in an emergency. I don’t know what kind of seduction tactics she might try, but if she pulls anything weird, I need a way to stop you.”

Of course, I left room for a bit of negotiation depending on the situation. I hesitated, then added:

“Then there’s the Consent for Third-Party Access and Use of Personal Information?”

“To observe her closely for a while and respond swiftly if anything suspicious happens. The prophecy says the change begins when she trips while walking through the garden.”

“And this one?”

Karian held up another document, wearing a strange expression like he was barely holding back laughter.

“Isn’t it obvious? It’s a Ritual Exorcism Consent Form. We’re dealing with a spirit here—it needs to be expelled. Don’t laugh. This is the most important one.”

Will I really be able to exorcise the mysterious soul… and stop my fiancé from falling out of love with me?
