Will you come back?

Jungkook fic. This book is inspired by the book Red Queen.
If you haven't read it, make sure to. It's amazing.
Anywho, just to clarify this book has no ideas or anything from the Red Queen. It was just an idea I came up while reading the book.
Description: Jungkook is your step brother who happens to be in the army. And you are just a slave trying to get promoted to servent for the king and queen. But what happens when they give you an offer you can't resist.
