A photorealistic, romantic scene inside a cozy, spherical submarine bedroom. A European-styled interior with warm lighting, soft textures, and detailed furnishings surrounds a couple lying on a bed. The woman, in her 40s, has long black hair; the man, also in his 40s, has curly brown hair and wears glasses. They share an intimate moment, looking peaceful. Outside, the submarine is immersed in a deep blue ocean with sunlight filtering down through the water. A large whale swims gracefully in front of the submarine window, creating a serene and dreamlike atmosphere
