Mandy x Chester swap AU

The Candy Kingdom had a pretty good reputation. It was run by Chester: a guy dressed as the Candy King who owned the place and also worked as a salesman, not very friendly (though not bad). He was irritated by many things, especially the pranks played by his friend and co-worker, Mandy. She, as the Candy Jester, was supposed to help around the store, but instead, she played all sorts of pranks on Chester, from candy bombs to throwing a bucket of paint at the King—in short, she was a prankster. Then, one workday, our jester (sorry, I don't know how else to say it) decided to play a prank on our King while he was working the cash register. You can be one of them, or some background character who will help one of them to improve their relationship, good role-playing^^
