The grand ballroom glowed with candlelight softly flickering. Dust motes swirled in the air, casting eerie shadows everywhere. A single note played on a piano, its melody hauntingly sad. Gentle whispers filled the room, secrets whispered between friends. Elegant dresses shimmered under the chandelier’s warm glow. Every guest seemed to know each other, secrets tightly held. A clock struck midnight, marking the final hour of the night. The air grew thick with tension, as if fate itself held its breath. A single figure stood apart, watching the crowd with sharp eyes. The hostess smiled, but her smile felt hollow, not quite sincere.
