提示词
15 秒的 2D 动画视频。镜头全程完全静止不动。在小学教室的一块大号绿色黑板上，画着两个简单的白色粉笔简笔人物，面对面站立（左边是男孩，右边是女孩，扎着马尾）。
分镜：
0-5 秒：左边的男孩简笔人物伸手到背后，拿出一朵白色粉笔画的花。他温柔地把花递给女孩简笔人物。周围出现小小的白色粉笔爱心。女孩简笔人物变得害羞而心动，一只手微微遮住脸，小爱心飘起。所有爱心和特效都严格保持在绿色黑板范围之内。
5-7 秒：突然停顿。两个简笔人物都愣住片刻。
7-15 秒：他们突然摆出激烈的空手道格斗姿势。两个简笔人物展开一场非常激烈的粉笔画风格空手道对决——快速的出拳、高踢、旋转和戏剧化的姿势。每次击中都伴随白色粉笔的运动线条、冲击星芒和尘土特效。所有运动线条、星芒、尘土和图形特效都完全保持在绿色黑板之内，绝不会超出黑板边缘。一切都以白色粉笔画的形式呈现在绿色黑板上。教室背景、课桌、椅子和海报保持完全静止、不发生变化。没有镜头运动。干净的 2D 动画风格，简单的粉笔线条画，只用白色粉笔，动作高度细致，时长 15 秒。
负面提示词：3D、写实人物、镜头运动、彩色粉笔、特效超出黑板范围、背景变化、模糊、低质量原文提示词（English）
15-second 2D animated video. Camera is completely steady and static the entire time. On the large green chalkboard in a elementary classroom, two simple white chalk stick figures are drawn facing each other (male on the left, female on the right with a ponytail). Sequence: 0–5 seconds: The male stick figure (left) reaches behind his back and pulls out a white chalk-drawn flower. He gently offers the flower to the female stick figure. Small white chalk hearts appear around them. The female stick figure becomes shy and kilig, covering her face slightly with one hand while little hearts float up. All hearts and effects stay strictly inside the green chalkboard. 5–7 seconds: Sudden pause. Both stick figures freeze for a moment. 7–15 seconds: They suddenly drop into intense karate fighting stances. The two stick figures start a very intense chalk-drawn karate fight — fast punches, high kicks, spins, and dramatic poses. White chalk motion lines, impact stars, and dust effects appear with every hit. All motion lines, stars, dust, and graphic effects remain completely inside the green chalkboard and never go outside the board edges. Everything stays as white chalk drawings on the green board. The classroom background, desks, chairs, and posters remain completely still and unchanged. No camera movement. Clean 2D animation style, simple chalk line art, white chalk only, highly detailed motion, 15 seconds. Negative prompt: 3D, realistic people, moving camera, colored chalk, effects going outside the board, changing background, blurry, low quality建议模型
