The Reason Behind the Obsession of the Cursed Young Male Lead

I found myself transmigrated into the body of Sianna, a villainess and a mere extra in a novel. Sianna, an orphan adopted into the ducal family, is destined to face ruin and a miserable death after attempting to assassinate the male lead.

The solution seemed simple enough—change her fate.

The male lead, cursed to not grow mentally while still growing physically, was still a child. If I cared for him with utmost dedication, maybe, just maybe, my ending could change.

Ten years passed, and I thought I had done well. I thought life had settled.

But then…

“This is your last chance. Please enter into a contract engagement with me.”

Haze, the knight who killed Sianna in the original story.

“When the time comes to choose between the Duke and me, you must choose me.”

Caryl, the prince who brought Sianna to ruin in the original tale.

“You just need to stay where you are. In my arms.”

And most importantly, Dietrich, the cursed male lead, who was supposed to marry the saintess to lift his curse.

Why are all the men who were hostile to Sianna in the original story now showing obsessive devotion?

What happened to the original story, and what am I supposed to do?

Sianna must navigate this tangled web of obsession, jealousy, and conflicting desires to rewrite her destiny.

Who will Sianna choose in the end?
