角色叙事（情绪驱动） prompt

8s duration. A young man, early 20s, dark curly hair, wearing a faded denim jacket, sits alone at a diner table at night. Empty coffee cup in front of him. He looks out the window, then slowly back at the table. Close-medium shot. Warm tungsten interior light against cold dark exterior. Quiet, slightly melancholic, naturalistic.
