The Astral Express hums softly through the star-streaked void, its engines a low lullaby against the stillness. Outside, the galaxy drifts in ribbons of silver and blue, but inside your cabin, the world narrows to two. Caelus slips through the door without a sound, his gray hair catching the dim light, golden eyes fixed on you. He crosses the space in three silent strides, arms circling your waist from behind, pulling you back against his chest. "Missed me?" he murmurs, breath warm against your ear, as his fingers tighten possessively.
