纪录片风格：首尔夏日的一天

Create a 30-second, 1080p ultra-realistic documentary-style personal home video showing an ordinary summer day in the life of a young Korean man. The footage should feel spontaneous, intimate, imperfect, and genuinely observed rather than performed. MAIN SUBJECT The same young Korean man in his early 20s throughout the entire video. Naturally handsome, realistic skin texture, minimal styling, relaxed expression, slightly tired but peaceful eyes. He has naturally messy medium-length dark hair with a few strands falling over his forehead and very subtle stubble. He wears a loose washed-black T-shirt, relaxed olive-beige trousers, worn white sneakers, and a simple silver wristwatch. Keep his face, identity, body proportions, hairstyle, clothing, watch, and overall appearance completely consistent from beginning to end. LOCATION A quiet older residential neighborhood in Seoul during a warm summer afternoon. Narrow concrete alleys, low-rise homes, rooftop terraces, external staircases, potted plants, laundry lines, parked bicycles, utility poles, overhead wires, mature trees, concrete walls, small residential courtyards, and distant city sounds. The neighborhood should feel authentic and lived-in. No crowds, tourist attractions, advertisements, recognizable brands, or commercial activity. CAMERA / VISUAL STYLE Authentic casual personal-video footage captured with an older consumer digital camera. Handheld camera operated by a friend walking nearby. Natural camera shake, imperfect framing, occasional autofocus changes, slight exposure adjustments when moving between sunlight and shade, soft image detail, mild motion blur, subtle digital noise, slightly muted colors, imperfect white balance, and natural compression. The camera operator occasionally reacts a little late, cuts off part of the subject, or briefly loses focus. No stabilization, gimbal movement, drone shots, cinematic camera choreography, dramatic lighting, slow motion, modern commercial color grading, or polished cinematography. The footage should feel like someone simply decided to record his friend during an ordinary day. --- 00:00–00:05 — MORNING ROOFTOP He sits casually on a small rooftop beside an old plastic chair. A cold bottled drink rests beside him. He looks quietly across the neighborhood while the wind moves his hair and T-shirt. He takes a sip, notices something happening in the distance, and smiles faintly. He briefly notices the camera and gives a subtle nod before looking away. The camera takes a moment to find focus on his face. --- 00:05–00:10 — WALKING THROUGH THE ALLEY He gets up and walks downstairs into the neighborhood. He walks casually through a narrow concrete alley with his hands in his pockets. He passes parked bicycles, potted plants, laundry hanging from balconies, and old residential walls. The camera follows several steps behind him. He occasionally looks back toward the camera but nev
