A Mystery, That Is

Hello, Author-Chan's a derp so:

I was inspired by my friend to make a Ciel x Reader/Ciel x princess!reader...

You haven't been in contact with anyone since that night. The night someone tried killing your mother and you, that is.
An old abandon castle is now reinforced with guards and traps so you can't leave, and no one can get in.
Your lady-in-waiting is the only person who keeps you from going insane, and that's alright, since she is also your only friend.
Then, you wake up, and you're not in the castle.
Who is this Ciel Phantomhive?
