The butler in black (female y/n X Sebastian)

Sebastian Michaelis is a devil serving the young master of the Phantomhive Manor, Ciel Phantomhive, who's family passed in a mysterious, unknown fire that had reduced the entire of the Manor to ashes. Ciel had also been presumed dead, his aunt, madame Red, thought he was gone. Until one day... One day he returned, with a shadow. The Butler in Black: Sebastian.
A crew worked alongside him: a dependent chef, who couldn't cook without at least some supervision, Baldroy.
He is a tough-minded, level-headed American veteran. With no difference to the other Phantomhive servants and helpers, he is a fiercely loyal man to the teenage ruler, and respects Mr Michaelis deeply.

Another member of the crew is Mey-rin. She is a magenta-haired maid of the household. It is clear she has a 'thing' for Sebastian, and is quite clumsy, yet her aim with firearms is immaculate.

Finny is also a part of the team that cares for Ciel. His strength has given many residents of the Manor problems, for it is uncontrollable for him. He is energetic and loud, but his personality can crack a laugh out of Ciel, although rare.

An old member of the circle of staff, Tanaka, has served Ciel and his family for many years. He is usually small when tired, but when he has the energy, he is tall and his words are as clear as crystal.

Last but certainly not least, we have you: Y/N.
You were a lost and lonely girl, everyone you loved gone. You stole food, but it was rarely enough to feed a young child, let alone a 19-year-old. Ciel found you when he wandered the surrounding wood of his home, and called Sebastian to collect you. He seems to have taken a liking toward you. The way you pronounced words weren't clear since you hadn't been educated for speech and writing. Even when fed properly, you hardly ate.
You try your best with the chores given to you, but your low energy restricts you... and the over-powering love for Sebastian distracts you.
