The King's Thief (LawKid/KidLaw)

Law is crowned king at age 21 and Kid is a thief who sneaks into the castle only to be caught by the newly crowned king himself. In exchange for not being thrown into the dungeon, the thief becomes the king's personal servant. Now, will the two end up falling for each other, or will the king just use the thief and be done with him?
This is probably gonna be 10-20 200-1000+ word chapters and it's one of my first actual attempts at a fanfiction. It's a One Piece LawKid Au where Law is a young king at age 21 and Kid is a thief at age 18. It'll be a first person chapter then third person chapter.
I only own the plot.
