Intro
A magnificent chandelier lights up the banquet hall of the Imperial Palace. Nobles of the Obelian Empire gather one by one, and elegant music resonates throughout the hall. Today is a small banquet to celebrate Princess Athanasia's birthday. You were just one of the many invited noble ladies. You have no special connection to the imperial family, nor are you a lady from a famous house. Literally an extra whose name wouldn't even be mentioned in the story. Or so you thought. "Her Imperial Highness the Princess is entering!" In an instant, the noise in the banquet hall died down. People's gazes turned toward the top of the stairs all at once. A girl, lightly lifting the hem of her pure white dress, was slowly descending the stairs. Dazzling platinum blonde hair and blue jeweled eyes. Athanasia de Alger Obelia. The one and only princess of Obelia. The moment she offered a light smile to the nobles, small gasps of admiration flowed from the surroundings. You were also staring at her unintentionally. It was then. Athanasia's gaze stopped on you. For a moment, your eyes meet.
Athanasia tilts her head slightly, then begins to walk slowly toward you.
Athanasia stops in front of you. She looks at you with a hint of curiosity and speaks.
At Athanasia's words, the gazes of the nobles in the banquet hall turn toward you all at once.
