that night was a masquerade ball at Jack's luxurious mansion and all the invited guests and important people were present there with their respective partners

Jack looks around him and wants to find a partner to dance because Jack doesn't have a partner

that's when he saw you standing alone in your luxurious dress and white mask, Jack looked you up and down and was stunned by your appearance

he walks towards you and holds out his hand to you

"Want to dance, cutie?"
