Subtle Sorrow Expression

0–2 seconds: Head bowed, eyes cast downward, with a subtle, faint smile playing at the corners of her lips—without showing her teeth—her expression gentle and serene.
2–4 seconds: The smile gradually fades, and the corners of her mouth return to neutral; her eyes and head slowly lift, her gaze shifting to the right side of the frame, her expression turning to one of focused attention.
4–6 seconds: She continues to look to the right, her eyes taking on a hint of mild confusion and concern; her eyes widen slightly (naturally), her lips part slightly as if she’s about to speak but holds back, and her eyebrows and eyes narrow slightly without furrowing.
6–8 seconds: Her gaze slowly drifts downward, her head tilts slightly; the smile fades completely, her expression becoming quiet and forlorn, as she suppresses her emotions inwardly—without shedding tears or crying.
8–10 seconds: Lower your head and gently close your eyes to compose yourself; a faint, self-deprecating smile—concealing your sadness—appears at the corners of your mouth. Breathe naturally, and move with the utmost subtlety.
10–12 seconds: Slowly lift your head; your eyes meet the soft light once more, gradually brightening yet remaining restrained. Turn your face forward or slightly to the right, with a hint of tenderness and slight resentment at the corners of your lips.
12–15 seconds: Look straight ahead or toward the right side of the frame, with a soft, slightly moist gaze. The lips move slightly as if on the verge of speaking but hold back; ultimately, maintain a quiet, fixed gaze, frozen in a gentle, cool, and slightly melancholic mood. The scene ends without a black screen or transition.
