Otome game CG illustration, extremely gorgeous and luxurious. A couple performing an underwater dance within a pillar of light in deep-sea ruins, wearing exquisite "mermaid-concept haute couture" (not real mermaids). Male Lead (Deep-sea Prince outfit): He does not have an actual fishtail, but wears sophisticated deep blue scale-patterned trousers. The legs feature a unique cut that flares out below the knees into a massive, metallic bionic fin-like hem that sways with the water like a real tail fin. His upper body is a translucent deep-sea silk shirt embroidered with ancient wave totems in silver thread, adorned with magnificent shoulder pieces and chains crafted from black pearls and deep-sea silver. Female Lead (Mermaid Princess outfit): She wears a stunning pearlescent gradient mermaid gown. The dress is covered in thousands of hand-sewn iridescent sequins and Swarovski crystals, simulating a gradient scale effect from pale pink to gold, shimmering brilliantly under the light. The massive train is the design's focal point, composed of countless layers of ultra-lightweight tulle, lace, and silk, spreading over two meters in diameter in the water, appearing like a giant flower blooming in the abyss. Her upper body features a corset embellished with pearls, shells, and gemstones, with flowing transparent ribbons wrapped around her arms. Divine light shining through, garments refracting light, bubbles, bioluminescent jellyfish. Dreamy, fashion editorial aesthetic, intricate clothing details, character close-up, facial expression close-up. 8k resolution.
