Fading Smile in Dusk Breeze

First, generate a close-up of the girl. Refer to this image: the image should be completely kept in the state it was at the beginning. Close-up of the girl, standing in the dusk breeze, her face slightly tilted, hair blown in front of her face, eyes calm, expressionless and emotionless. The camera is handheld close-up, with slight breathing movements, like the camera is on but the actors haven't started the performance yet. A very soft voice came from outside the painting: "Alright, let's begin." After hearing this, the girl began to perform. She slowly shifted her gaze to the camera, first flashing a sweet, natural smile, as if trying to reassure people. Her smile was very clean, the corners of her mouth gently lifted, and her eyes curved along with her. For the first two seconds, there was no sign of sadness at all. The wind kept blowing, and a few strands of hair stuck to her face, but she didn't tidy it up. The smile remained, but his gaze gradually became a bit empty. It's not an outburst of sadness, but rather that after laughing for too long, the facial muscles are starting to give up. The corners of his mouth still smiled, but the light in his eyes gradually dimmed. In the last two seconds, she still smiled at the camera. Only the nostrils twitched slightly, his throat felt like he had swallowed, his eyes a little moist, but no tears fell. She tried hard to keep a sweet smile on her lips, but her eyes showed fatigue. Finally, she gently lowered her eyes, then looked up, as if suppressing her emotions back down, 3:4
