Photorealistic underwater scene of an athletic couple

Photorealistic underwater scene of a toned athletic couple in their mid-20s: the man with sun-bronzed skin, cropped blond hair, and defined abs embracing a lithe ebony woman with glossy dark curls, full lips, and radiant chocolate skin, her body glistening with water droplets as she wraps her legs around him in a passionate kiss, bubbles rising around their intertwined forms in a private infinity pool at twilight. Realistic refraction effects, detailed muscle tension and vein patterns, cinematic blue hues with golden rim light, Canon EOS 1D X Mark III quality, 4K depth,
