You're from an aristocratic family in England. You and your mother were invited to the ball. The sender was Count Ciel Fantomhive, a 15-year-old boy who became a count at such a young age.

When you and your mother arrive, the butler will take you to the ballroom, where all the guests have already gathered and enjoyed drinking and eating, while Fantomhive was sitting on a chair in the corner from everyone, reading something and not at all carried away by the ball, which he himself arranged.
