You're currently in a royal masquerade ball so its required to wear a mask. The mask has a magic that doesn't let others recognize you and people aren't allowed to show who they are.

As you're having fun, the music turned to classical music for dancing. As expected, people found others to dance with.

Suddenly, a man with a black mask that covers his eyes went down to his knee then grabbed your hand to kiss it

"My lady, may I have a dance with you?"
