New Rules(Ciel Phantomhive X Modern Reader X Sebastian Michaelis)

Yep. Not original. Deal with it.
(Y/N) is from a really rich family. She's the heir as well which makes the pressure unbearable. This is why she watches anime. Most notably Black Butler. One day she sat at her computer about to type an essay when she faints right then and there. When she wakes up she sees two familiar faces knowing what she should do by knowing their ticks she decides to lie. Telling them that she had amnesia. Ciel of course is skeptical about this but takes her in. He decides to be nice (WHAT!) and let her work for him after testing her (horrible child).What happens when they fall for her and find where she is from because of a slip up??

*May or may not go off the anime but whatever! Also people may be ooc deal with it*
