主要请求：创作一张照片级逼真的图像，主角是一名虚构的 20 多岁成年韩国女性偶像，不应与任何现实中的名人相似，呈现一种从容但私密的时尚肖像氛围。
场景/背景：小型海岸气象站平台、混凝土台阶、淡色仪器箱、一个简单的风向标、薄薄的海雾、柔和的云层，没有可读的标签。
主体/服装/姿势：她身穿银灰色防风衣，内搭奶油色针织上衣，穿着炭灰色百褶中长裙，搭配不透明连裤袜和极简白色运动鞋。她坐在混凝土台阶上，一只膝盖抬起，一只脚较低，手持一根刚好在画面外的哑光白色气象气球的绳子，另一只手支撑在台阶上。头发在风中轻轻飘动；表情疏离，双唇放松。
风格/媒介：日本负片胶片美学、柔和的自然海岸光线、轻微过曝的雾气高光、低对比度、柔和褪色的色彩、细腻的颗粒感、不完美的构图、记忆般的写实感。
约束条件：成年主体、品味高雅的非色情时尚肖像、无裸露、无未成年人、无标识、无可见文字、无水印。
避免：屋顶、冷瓶子、塑料袋、白色大码衬衫、短裤、戏剧性的科幻实验室外观、现实中的名人长相。

Primary request: Create a photorealistic image of a fictional adult Korean female idol in her mid-20s, not resembling any real celebrity, with a poised but private fashion portrait mood.
Scene/backdrop: a small coastal weather station platform, concrete steps, pale instrument boxes, a simple wind vane, thin sea fog, soft clouds, no readable labels.
Subject/clothing/pose: she wears a silver-grey windbreaker over a cream knit top, a pleated charcoal midi skirt over opaque tights, and minimal white sneakers. She sits on the concrete step with one knee raised and one foot lower, holding the string of a small matte white weather balloon just out of frame while her other hand steadies against the step. Hair moves gently in the wind; expression distant, lips relaxed.
Style/medium: Japanese negative film aesthetic, soft natural coastal light, slight overexposed fog highlights, low contrast, muted faded colors, subtle grain, imperfect composition, memory-like realism.
Constraints: adult subject, tasteful non-explicit fashion portrait, no nudity, no minors, no logos, no readable text, no watermark.
Avoid: rooftop, cold bottle, plastic bag, white oversized shirt, shorts, dramatic sci-fi lab look, real celebrity likeness.
