In a surreal world where buildings can be constructed, the buildings are depicted as floating on the surface of the ocean. Each building is unique in its design, but there are different types of inhabitants that thrive in the stillness of water. The water's surface is a dazzling blue, and the surface of the water is so calm that it almost seems to glow under the soft light of the setting sun. Sea level erupts in an otherworldly way, and people around the building move calmly, their faces illuminated by the radiant light of the sun's rays. This is a scene of pure tranquility, enticing anyone who dares to explore its limits.
