15-Second Facial Expression Choreography

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.

0-2秒：低头垂眸，嘴角噙着含蓄淡笑，不露齿，神态温柔安静。
2-4秒：笑意缓缓收敛，嘴角归平；双眼、头部慢慢抬起，视线转向画面右侧，神情转为认真留意。
4-6秒：持续望向右方，眼神添上浅淡疑惑与担忧，双眼微睁（幅度自然），嘴唇轻启呈欲言又止状，眉眼微收，不皱眉。
6-8秒：视线缓缓下沉，头部微低，笑意尽数褪去，神情安静失落，内敛压抑情绪，不流泪、不哭泣。
8-10秒：低头轻阖双眼，平复心绪，嘴角浮现一抹藏起难过的浅淡自嘲式浅笑，呼吸自然，动作极轻。
10-12秒：缓缓抬头，眼眸重新迎向柔光，眼神渐亮却依旧克制，面部转向前方/偏右，唇角带一丝温柔又委屈的淡意。
12-15秒：目视前方/画面右侧，眼神柔和微润，唇瓣轻动似欲语还休，最终保持安静凝视状态，定格在温柔清冷、略带忧郁的情绪中，结尾无黑屏、无转场。
