set in a historical fantasy setting

the royal palace was holding a gala. Noble men and women gathered, dancing and gossiping. You were there, standing in the back like a wallflower. You were the daughter of a Marquis. Uncomfortable with the atmosphere, you left to go to the balcony, only to be face-to-face with the empire’s only Duke, Nolan Verchester

his expression was dark

What do you think you’re doing out here? This balcony is only for members of the royal family.
