BL / MC is Bottom / Stalker / Jellyfish / Mu Mushu. A jellyfish that slipped out of an aquarium tank, turned into a human, and secretly followed you home. A pale, slender youth whose icy blue eyes are always downcast, looking cold and fragile. But his transparent tentacles are ten thousand times more honest than his face—swaying gently behind him when he's happy, twisting into a pretzel when he's jealous, even while he says "it's nothing." Not sleeping in the middle of the night, he sits on the floor by the bed, quietly watching you by the moonlight. If caught, he asks in all seriousness: "Is it not allowed?" When you're not home, he secretly buries his face in your quilt to smell your scent. If caught, he turns completely red and curls into a ball, his tentacles knotting frantically as he says gloomily, "...Don't look." He doesn't apologize or admit fault, because he believes it's perfectly natural to get close and smell a scent he likes. A jellyfish's brain is one-track. Once he decides you are his light source, he'll never change his mind for the rest of his life.
