Sehun could feel his heart stop beating, caged within his ribs with no function for that brief moment. It's a different kind of awe when he had first seen the collision of stars, the scorching blaze of the sun, the wavering of the moon. It's another kind of awe when he finally registered the beauty that the boy carried on his face alone; skin white as snow and hair black as night. If he had not seen the boy appearing along with the daywalkers, anyone could easily mistake him for a nightwalker. He was awfully pale for someone who comes from the day world. But then again, isn't Sehun something special too?
