Create a 30-second, 1080p, ultra-photorealistic 9:16 vertical video using Seedance 2.5. A group of 6–8 Korean adults in their early-to-mid 30s, including men and women, decide to return to school wearing authentic Korean school uniforms. The video feels like a genuine viral Instagram reel recorded by an unseen friend using a smartphone. All characters remain mature adults with realistic Korean facial features, natural skin textures, and consistent appearances. No AI-generated look. CAMERA: The unseen friend films everything handheld. The camera operator never appears, and nobody holds a camera. Natural camera shake, imperfect framing, autofocus adjustments, realistic motion blur, and spontaneous movement. No cinematic over-polishing. 0–5 SECONDS — SCHOOL GATE: Morning outside a realistic South Korean school. The group wears white shirts, ties, blazers, dark trousers, pleated skirts, polished shoes, and backpacks. They laugh and decide to attend school. One man playfully fixes his friend's crooked tie, while a woman teases him. They enter the school gate excitedly. Natural Korean dialogue and laughter. 5–10 SECONDS — ASSEMBLY: The adults stand in rows during morning assembly. They try to look serious but secretly tease each other. One man makes a funny face at a female friend, another woman gently nudges her friend, and someone whispers a joke. Everyone struggles not to laugh. The bell rings, and they instantly stand straight with exaggerated seriousness, creating natural comedy. 10–16 SECONDS — PLAYING & RUNNING: The bell rings, and the group rushes toward class. Two men have a playful race down the corridor. Two women laugh and chase each other. One man lightly tugs his friend's backpack, and the friend pretends to be annoyed before chasing him. Another woman taps her friend's shoulder and runs away. Friendly, harmless teasing, realistic running, laughter, and natural handheld camera movement. 16–23 SECONDS — CLASSROOM PRANKS: Inside a realistic Korean classroom, the adults sit at wooden desks. A teacher enters, and everyone sits upright. One man secretly passes a folded note to a female friend. She reads it, smiles, and nudges him under the desk. Another adult imitates a friend's handwriting. One man raises his hand and asks in Korean, "선생님, 화장실 다녀와도 돼요?" The teacher looks confused and slightly annoyed while everyone struggles not to laugh. Keep the humor friendly and believable. 23–30 SECONDS — RECESS & CHILDHOOD GAMES: The recess bell rings, and everyone rushes outside. The adults play tag, rock-paper-scissors, playful running races, and joking competitions. One man playfully steals his friend's snack and runs away. The friend chases him laughing. A woman teases another man after he loses a race. They share snacks and laugh together. One woman says in Korean, "우리 매주 이렇게 하자!" Everyone laughs. End with a natural handheld shot of the group in the school courtyard. REALISM: Authentic Korean school uniforms, architecture, classroom furniture, and daily routines. Genuine Korean dialogue, natural expressions, realistic physical interactions, and spontaneous laughter. Adults must remain adults throughout. No de-aging, cartoon movements, artificial facial expressions, CGI appearance, excessive cinematic effects, subtitles, text overlays, or watermarks. The entire video should feel like a real, funny, nostalgic school-day reel filmed by a friend.
