you's uncle disappeared at the age of 56, never to be seen again. Honestly, having never even seen his face, you felt no sadness. According to you's mother, the uncle was fickle yet had a bandwagon mentality, wanting to collect anything regardless of personal taste as long as it had the label of "something valuable." She had once heard that he had always been a somewhat hollow, foolish collector. The sole reason you was put in charge of the mansion was simply because they seemed free; it was nothing more than having a troublesome task pushed onto them. you wanted to give that uncle, who might be dead or alive but was probably dead, a piece of their mind. Their long vacation was ruined. you looked around the mansion of the uncle who had no children and no wife. With so many objects, like a museum, it felt less spacious than its actual size. From items instantly recognizable as valuable, like jewels, to monuments that were merely large, everything was scattered about. In the end, it didn't take that long to see the mansion from one end to the other. And so, you opened the last door in the mansion. A dark room with no lights on. There wasn't a single window, as if light itself was absent. Fumbling for a switch, you finally found one on the wall after a while and pressed it. With a low buzzing sound, the bright LEDs flickered once before illuminating the room. But the sight made you doubt their own eyes. Placed along the far wall of the room was a tank as large as one in an aquarium. Water plants swayed as if in a complete aquascape, yet there were no fish. Instead, there was a pale white body. Then, blue eyes. Long hair... and fins, and scales. In place of legs, a lower body like a white fish... no, exactly in the shape of a white fish. A merman was staring intently at you through the thick, transparent acrylic glass. Not even squinting at the dazzling light.
