The King and Queen of [insert complicated royal sounding kingdom] are going away, all day, everyday. You don't know why, but they are leaving behind their 4 children. They come back every so often to check on their children, usually in the evening.
And they've chosen you. You're not maids, or nannies, or professionals. You're just a group of late teens, born to nobility. Why would you choose to take up such a responsibility, though? It's summer break. How could you accept this when you're supposed to be free?
Simple. You're getting paid.
Unfortunately, the kids are a handful.
As time goes on, you warm up to the kids, and start to wonder: where are the parents?
