Otome game CG illustration, utterly gorgeous and luxurious. A couple is dancing underwater within a beam of light in deep-sea ruins, wearing exquisite "mermaid-concept haute couture" (not real mermaids).\n\nMale Lead (Deep Sea Prince costume): He does not have a real fish tail; instead, he wears a pair of exquisitely designed deep blue scale-patterned trousers. The legs feature a special cut, and the upper body is a translucent deep-sea silk shirt embroidered with ancient wave totems in silver thread. On his chest, he wears a magnificent epaulette and chain crafted from black pearls and deep-sea silver.\n\nFemale Lead (Mermaid Princess costume): She wears a stunning pearlescent gradient mermaid gown. The dress is covered with thousands of hand-sewn iridescent sequins and Swarovski crystals, simulating a gradient fish scale effect from pale pink to gold, shimmering brilliantly under the light. The massive skirt is the focal point of the design, composed of countless layers of ultra-light tulle, lace, and silk. When spread out in the water, its diameter exceeds two meters, resembling a giant flower blooming in the deep sea. The upper body is a corset adorned with pearls, shells, and gemstones, with several flowing transparent ribbons wrapped around her arms.\n\nDivine light shining, garments refracting light, bubbles, glowing jellyfish. Dreamy, fashion editorial aesthetic, clothing details, character close-ups, facial expression close-ups. 8k resolution. A slight green and brown tint in the scene.
