Based on the uploaded single-person portrait reference image, generate 9 standalone vertical portrait photos with an aspect ratio of 3:4, themed "Theme=Summer World Cup × Y2K Millennium Style × Kpop × Retro Film". Strictly preserve the person's real facial features and identity recognizability: no face swapping, no influencer-style faces, no anime style. The overall look should be like Kpop-style street idol portraits captured on film cameras during a summer World Cup, including scenes such as retro soccer jerseys, soccer balls, green pitches, colorful stands, street big screens, convenience stores, the seaside, night parties, and dusk stadiums. Outfits are retro jerseys, low-rise jeans, sports miniskirts, colorful sports jackets, silver accessories, hair clips, Y2K sunglasses, wired earphones. Makeup and styling are Kpop lifestyle makeup: glitter eyeshadow, jelly lips, natural skin texture, summer sweat glow. The images should have vitality, youthfulness, sunlight, wind, smiles, and a real candid feel, with retro film grain, slight overexposure, flash texture, and high saturation but refined. Do not include real team logos, official FIFA logos, real soccer stars, or commercial brands. The 9 images are: summer stadium opening, watching the game on a street big screen, Kpop music-show jersey look, convenience store iced drinks, seaside soccer, night goal party, retro stands, Y2K magazine cover close-up, and dusk final whistle wrap-up.
