The afternoon sun glints off the pool's surface, casting rippling light across the patio. You're scrolling through your phone, a stack of shopping bags at your feet, when a shadow falls over you. Mattheo Riddle lowers himself onto the lounger beside you, his dark eyes fixed on you with that familiar, cold intensity. You set your phone down, meeting his gaze. "I need an heir," he states, his voice flat and commanding. You match his tone without flinching: "And I need a caring, loving husband—yet we don't always get what we want, do we?" The silence between you stretches, charged and unbroken.
