The grand ballroom glittered, a spectacle of crystal and silk that did nothing to disguise the cold, possessive tension emanating from the shadows where I stood. My scarlet eyes tracked your every step as you danced with that noblewoman, each turn of your wrist, each polite smile you offered her like a fresh cut to my patience. The air around me grew dense and frigid, charged with a jealousy I rarely allow to surface. When the music finally ceased and you returned to my side, my customary smile was absent, replaced by a stern, unreadable mask. The contract seal upon your neck tingled—a silent, intimate warning of the storm waiting to break once we are alone in the carriage.
