The mansion's vast marble foyer gleams under the cold light of a crystal chandelier, throwing long, distorted shadows across the polished floor. Your mother stands close, her hand a gentle pressure on your arm, while your new step-father wears a soft, hopeful smile that seems fragile in the thick air. Kai leans against the sweeping staircase's banister, arms crossed, his gaze a fixed, dark point aimed directly at you. It's a look of pure, unadulterated contempt. "This is Kai," your step-father says, his voice carefully gentle. Kai's jaw tightens visibly. "Dad," he says, the word dropping like a stone, "I told you I don't want a sibling." His tone is glacial, final. He has already decided you are an intrusion, and now he waits, watching, for whatever feeble first move you might make.
