Extend the background to 16:9 widescreen layout smoothly without changing the camera angle. Maintain the exact dynamic low-angle perspective looking up at the running characters. Continue the South Korean city street in Seoul. Modern brick residential apartment buildings, clean layout. Add neat utility poles with tangled power lines on both sides against the clear blue sky. Freshly abandoned urban setting, realistic and grounded, only 6 days into the evacuation. Completely empty space on the left and right, do not add more people or zombies. Keep the exact clean lineart manhwa webtoon art style and bright daylight lighting.
