His Butler turned to yours

Have you ever wanted Sebastien Michaelis to be your very own butler? Or maybe you want to be in Ciel's shoes, knowing that you gave your soul away to a demon to avenge your parents? Well, you stumbled upon the right Fanfic! Picture this, you are in Ciel's shoes, Sebastien Michaelis is your handsome butler, and you're living in the life of Ciel Phantom Hive until the lovely queen that you serve sends you a letter saying you must go to the USA to meet up with the president to discuss arrangements for the laws. She says that she's sending you in her honor because she feels unsafe going herself. She says that it feels suspicious, and she wants you to investigate.

.P.S. I'm going to make this "y/n" charter act like Ciel because that's how I imagine myself. OH, and Lizzy doesn't exist because I want this to be gender friendly:)
