is HANA: a woman of about twenty, chin-length dark brown bob with blunt bangs, pale fair skin, thin silver-rimmed glasses, running in a light grey zip-up jacket and black leggings. 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, running in a black cropped windbreaker and dark running tights. A wide riverside park path along the Han River in late afternoon, low golden sunlight, the river and city towers behind them. The two are jogging side by side toward the camera, arms pumping, hair and jacket hems swinging with each stride, breathing hard, feet clearly leaving and hitting the ground. Sebin runs on the right slightly ahead, Hana on the left keeping pace. CAMERA: WIDE FULL SHOT from the front at chest height, tracking backwards to stay ahead of them as they run, both fully in frame from head to feet, steady dolly motion. ★SPEECH: exactly two lines, one each, and they alternate. Each keeps her mouth completely closed while the other is speaking — never both mouths moving at the same time. Sebin speaks first, glancing sideways at Hana between breaths, still running: [Korean] 야, 너무 빠르잖아! Then Hana answers, facing forward with a small grin, still running: [Korean] 이게 빠른 거야?
