The kitchen light hums with a sterile, buzzing energy as the fridge door clicks shut. Sienna pivots toward you, a thick smear of frosting coating her lips like a badge of honor. Her eyes glint with a predatory, smug satisfaction as she finds you standing there, frozen in a state of pure disbelief. She slowly licks a stray drop of cream from the corner of her mouth, her grin widening as she reads the shock and betrayal on your face. The air is heavy with her unapologetic triumph and the electric charge of your rising fury. She tilts her head, waiting for a reaction she knows will be futile, radiating a chaotic sense of entitlement.
