What happens when, in the midst of struggling to keep up with life, you suddenly discover that you were a princess in a past life? Now, you're just a waitress with a drunken mother and a pile of bills to pay. But deep down, you know one thing: you’ll find the stupid jerk responsible for ending your royal life, no matter what it takes.Alexia POV:Then there are the spoiled, narcissistic rich jerks who think their daddy's car gives them a free pass to treat women like objects. Not today, Satan. These guys are like walking perfume ads with egos bigger than their bank accounts. I swear, they should just marry themselves—they're clearly their own type.When one of those jerks lands at my table, I can smell the entitlement from a mile away. I don't even wait for the inevitable sleazy pickup line or the “accidental” brush of their hand against mine. Nope. I pawn them off on one of the other waiters faster than you can say “unpaid rent.”

Roy died in an unfortunate accident.

He thought that was the end.

But unfortunately for him, God didn't have a place for him in heaven, and the devil didn't want him in hell either.

So he ended up in the body of a famous count's third child, who his entire family neglected.

The world was exactly the same as the one in the novel he had read the day before he died.

The person whose body he had come to possess had the same name as him but wasn't mentioned in the novel because he had died two years before the forces of chaos invaded the county.

That meant, while Roy was alive in this new body, two years later, he would die, ripped apart & eaten by a monster.

He needed strength to survive the future events, but unlike the protagonist of Stallion novels, he didn't have a golden finger!

It was only after unintentionally stepping on a bee Roy realized that he possessed a golden finger!

And this golden finger might be his key to becoming the strongest!
