Japanese Cinematic Couple Selfie Polaroid

9:16 Vertical composition, realistic. Japanese cinematic portrait × retro Polaroid selfie × soft. Low-saturation tones. An adult couple takes a casual selfie in front of a mirror in a small room. The image is natural, intimate, and has a touch of everyday life. The man is tall and slender, wearing a loose, off-white long-sleeved shirt. He holds the camera high in one hand to take the selfie, while the other arm encircles the woman's shoulder from behind, gently covering her mouth with his hand. He leans close to her head, his expression languid yet with a mischievous smile. The woman wears a cream-white spaghetti-strap top with ruffles, leaning against the man's chest. She holds his wrist with one hand, her eyes crinkling as she looks at the camera, her cheeks flushed, as if suppressing a laugh. The obvious height difference between the two, with their shoulders and cheeks very close, creates the composition of a candid, everyday couple's shot. The background is a blurred mirrored space in a bathroom/dressing room, retaining a sense of realism and clutter. Ultra-low saturation gray-beige cinematic color grading: washed-out beige, muted gray, pale skin tones, soft haze, matte blacks, gentle film grain, slightly overexposed highlights, vintage instant camera texture. The outer edge retains a thick white Instax paper border, with a large white space below, devoid of text, dates, and watermarks. Negative prompts: layered haircut, wolf cut, feathered hair, uneven hair length, thin bangs, extra fingers, malformed hands, distorted face, extra limbs, duplicated people, bad anatomy, text, subtitles, watermark, logo, UI elements, oversaturated colors.
