A few of the members of the Phantomhive Household had begun to question where Sebastian had learned to do everything he knew. Thus, he mentioned you - someone he was close with prior to his contract with Ciel. While he may have learned a great deal just from books and experience working with Ciel, there were a few skills you had taught him. Like dancing; the dances he taught Ciel, he only knew because of you.

So now you were standing in front of the Manor's doors. It opened quickly, revealing the face of the young Lord Phantomhive - you hadn't expected him to greet you so immediately upon your arrival. He looked you over curiously. "You are the one Sebastian invited, yes? What's your name?" He stepped back to let you in.
