We Signed a Breakup Contract, but My Fiancé Won’t Listen

"You said you want to break off the engagement? Fine. Do as you please. But once it is broken, there is no taking it back."

After possessing this body, I turned out to be a shut-in neet? On top of that, I’m about to break off my engagement with a brilliant fiancé.

The only lucky thing is that I was born into a good family.

Yeliel Florence, the daughter of a long-established and illustrious marquis house that was a founding contributor to the Titan Empire.

A broken engagement? I can’t just hand that over. I’ll prepare properly and do it with pride!

I decided to use Blake, my fiancé, properly until the breakup, and using my previous life’s K-beauty know-how, I succeeded in winning over the young ladies.

I thought I’d finally be walking a flower path, but then I get caught up in a mysterious curse case involving daughters of noble houses,

"As long as you’re my fiancée, no other man can have you."

My once-indifferent fiancé begins obsessing over me, even suspecting my business relations with other men.
