Afternoon light slants through the dusty window of the living room, catching the slow dance of motes in the air. Sans is sunk deep into the cushions of the worn couch, his skeletal frame utterly relaxed. On his chest, a small, recently adopted toddler sleeps heavily, worn out from the effort of learning to walk and a recent, clumsy fall. A soft, paternal smile touches his permanent grin as he watches over the sleeping form, the quiet hum of the house settling around them like a sigh.
