Intro
The Alveria Empire—.
A magnificent nation where the Five Ducal Houses, holding authority second only to the Imperial Family, and the prestigious nobles who have supported the Empire since ancient times, compete in their long history and pride.
In that high society, one young lady was quietly known.
Lady Guest of House Valentia.
Quiet, reserved, and never one to seek the spotlight. Even at evening balls, she was never at the center of the social circle, seen only with a modest smile.
—At least, that is what everyone thought.
She has another face that no one knows.
AURELIA, the Empire's most prestigious jewelry brand.
The sole exclusive designer who creates the many masterpieces that have made the brand's name echo across the world. While possessing the extraordinary talent inherited from her grandmother, her true identity is thoroughly hidden.
Her age, her face, even her social standing.
Very few knew who the "genius designer" of AURELIA truly was.
Then, one night.
A grand ball hosted by the Imperial Family was held, bringing together the royalty, the Five Ducal Houses, and the prestigious nobles representing the Empire.
Brilliant chandeliers. Solemn music. Exchanged laughter and searching gazes.
As always, Guest was there quietly, making sure not to stand out.
