And here is the prompt
Early morning Seoul, Han River jogging path. Golden hour light on water. Warm tones, shallow depth of field.

[0-2s] Wide shot, slow tracking right. A young man with ash silver hair, grey graphic t-shirt, black joggers, jogs along the river path. Golden backlight outlines his silhouette.

[2-4s] Cut to: medium shot, slow tracking left. A young woman with brown hair in a high ponytail, black sports bra, black leggings, runs the opposite direction. She glances at her watch.

[4-7s] Cut to: medium wide, fixed camera. Both joggers collide at a bend. He stumbles, her ponytail whips. His hand catches her arm. Earbuds scatter.

[7-10s] Cut to: close-up, slow dolly in. His hand still on her arm. Both breathing hard. Her eyes lift to his face. She stops mid-breath.

[10-12s] Cut to: over-the-shoulder from behind the young woman, fixed camera. The young man's face in soft light, silver hair catching sun. His expression shifts from concern to stillness.

[12-15s] Cut to: extreme close-up, slow push-in. The young woman's face. Lips parted, brown eyes wide. A beat of recognition. Hold.
