Probably every servant's worst nightmare was to serve the feared King Choi San. His cruel words and even crueler actions left people shivering and bowing down to him in horror. His name was spoken in whispers and no one dared to complain about him since badmouthing the King would only mean a painful death. Nobody knew who to trust. Anyone could report their closest friend.
San had become the King after his parents, the previous rulers, died mysteriously. He didn't have a wife. Only a cruel person could send their daughter to marry a man so notorious. Only a cruel person could send their child to become a servant in said man's castle.
Still there you were, shaking and standing behind San's bedroom door after your mother had allowed the royal guards to take you away from home. Surprisingly, it was the King's order to have you become his personal servant. Sure, you were from a noble family and you had always known you would likely become a servant for someone higher up but you didn't want nor expect this.
"Come in," San's voice could be heard from his surely grand bedroom. Somehow, he had known you were behind his door.
