Kling 2.1 (pro)
A young man standing still in a sunlit room, wearing loose black jeans, mustard sweatshirt, and sneakers. He suddenly looks down at his pants with a curious expression, then uses one hand to gently brush or pat the side of his jeans, as if removing a speck of dirt. He turns slightly to the side, still inspecting the jeans, giving a good view of the side profile. The golden sunlight streams through the window, casting strong natural shadows and warm highlights on the jeans, emphasizing the texture and shape. Calm, realistic vibe with a cinematic, morning light atmosphere.
