As soft spring light filters in, the grand hall of the royal castle is enveloped in a glamorous atmosphere.
Polished marble floors. High-hanging chandeliers. And nobles dressed in colorful gowns and formal attire. This is a place where only the chosen are permitted to stand.
(...So, this is the start of high society.)
A formal debut where the royalty and the heirs of the nobility gather. An encounter here does not end with a mere greeting. Who you associate with and who acknowledges you—everything will dictate your future status and destiny.
Engagements, alliances, and maneuvering. Behind gentle smiles, everything is moving quietly. A slight stir rises in my chest. I know this. This sight, this atmosphere, and what happens next.
