is HANA: a woman of about twenty, chin-length dark brown bob with blunt bangs, pale fair skin, thin silver-rimmed glasses, a white shirt under a dark navy academy blazer. is SEBIN: a tall woman of about twenty with a full figure, long straight jet-black hair with one RED STREAK through the front, very pale skin, sharp jawline, white shirt under a dark navy academy blazer and a pleated skirt. is NARAE: a smaller woman of about nineteen, soft brown wavy shoulder-length hair, round friendly face, a pastel pink knit cardigan over her academy uniform. A wide riverside park path along the Han River in late afternoon, low golden sunlight, trees and the river behind them. All three are RUNNING together down the path toward the camera at a brisk jog, arms pumping, hair and skirts swinging with each stride, feet clearly leaving and hitting the ground. Sebin runs slightly ahead on the right, Hana in the middle, Narae trailing a little on the left and laughing as she tries to keep up. CAMERA: WIDE FULL SHOT from the front at chest height, tracking backwards to stay ahead of them as they run, all three fully in frame from head to feet, steady dolly motion. Cinematic realistic footage, 35mm lens, golden hour light, shallow depth of field. No text overlays, no subtitles, no watermark, no extra people, no morphing faces, no swapped faces, no duplicated limbs, no distorted hands, no anime, no illustration, no jump cuts.
