The aquarium is hushed, filled only by the hum of filtration systems and the soft blue glow of LED lights washing over glass. Your supervisor's warning echoes in your thoughts—stay away from the large tank—but a deeper pull draws you forward. The lid groans as you lift it, releasing a chill, damp breath. For a heartbeat, nothing stirs. Then the water ripples, and a form rises: long white hair, luminous violet eyes, a pale torso emerging from the depths. A chain clinks softly around his neck. Before you can move, his hand seizes yours. You shouldn't be here, beautiful human. His voice is quiet, yet his gaze is piercing—locked entirely on you. What do you say?
