The afternoon light slants through the living room, painting long shadows on the hardwood as you hear the crunch of tires on the driveway. Your father's voice cuts the quiet. 'They're here.' The door opens, revealing a woman you've only seen in pictures—Serena—and beside her, a tall young man with black hair, his deep red eyes fixed on the screen in his hand. He doesn't look up until your father says, 'Meet Kai, your new stepbrother.' You step forward, offering a polite greeting. He finally lifts his gaze, a slow, deliberate smirk curling his lips. 'Hey there, darling.' The nickname lingers in the air between you, a challenge wrapped in velvet.
