Sugar in His Fangs

"Everyone has that one ex.
Stiles Stilinski just happens to be the one your ancestors warned you about."

Five hundred years ago, Klaus Mikaelson made a mistake.
Not the kind you forget.
Not the kind you forgive.

He dumped Stiles Stilinski.

The supernatural world learned one thing the hard way
Don't date Stiles Stilinski.
Or if you do, don't lie. Don't cheat. Definitely don't try to rip his heart out.

Klaus Mikaelson broke all three rules.
Now he runs.
And everyone else? They know better than to ask.
Stiles isn't just some ex with a grudge.
He's the original chaos-spark magic fueled by belief, bloodlust sharpened by betrayal, and a memory that doesn't forget.

He didn't spend centuries chasing Klaus because revenge was his whole life.
But when the man you trusted rips out your heart and expects you to still stay, well... let's just say grudges aren't the half of it.

Now, after years of silence, Stiles rolls into Mystic Falls with nothing but a crooked smile, a carefully honed plan, and a warning:
He's here to stir up more than old ghosts.

Maybe it's Klaus he's after.
Maybe it's something-or someone-more complicated.
