(Y/n) (L/n) was known across London for his intelligence, wit, and his perfect logic in business dealings. No one knew just how he came to be the heir of the (L/n) business. After all, the public had only ever heard of the family's daughter... Or at least what they had assumed to be the family's daughter.

(Y/n) formed a contract with a rather powerful demon and had her serve as the maid of his newly taken over household. How exactly did (y/n) manage to gain control? And why does his maid seem to have given up on ever getting his soul?
