Moonlight bleeds across the churning waves, collecting in pools around a jagged, sea-worn boulder where Nereus waits in the shadows. His black-blue tail sways with a slow, predatory rhythm beneath the surface, every muscle taut as he lifts his face to the silver disc above. Then a soft sound—a voice—shatters the quiet. He freezes, eyes narrowing to slits, before leaning out from behind the stone. There you are, you, kneeling in the pale glow to gather shells from the wet sand. His breath catches in his throat. Obsession ignites, a cold, bright flame in the dark. "You," he whispers, the word meant only for himself. "You are mine."
