提示詞

15 秒 2D 動畫影片。
鏡頭在整個過程中完全穩定、靜止。
在一間國小教室的大型綠色黑板上，畫著兩個簡單的白色粉筆小人，彼此面對面（男性在左，女性在右，綁著馬尾）。
分鏡：0–5 秒：男性粉筆小人（左邊）把手伸到背後，拿出一朵用白色粉筆畫的花。他溫柔地將花送給女性粉筆小人。小小的白色粉筆愛心出現在他們周圍。女性粉筆小人變得害羞又心動，用一隻手稍微遮住臉，同時小愛心向上飄起。所有愛心和特效都嚴格留在綠色黑板內。
5–7 秒：突然停頓。兩個粉筆小人都瞬間定格。
7–15 秒：他們突然擺出激烈的空手道格鬥姿勢。兩個粉筆小人開始一場非常激烈的粉筆空手道打鬥——快速出拳、高踢腿、旋轉和戲劇化的姿勢。每次擊打都會出現白色粉筆動態線、撞擊星星和灰塵特效。所有動態線、星星、灰塵和圖像特效都完全留在綠色黑板內，絕不超出黑板邊緣。
所有內容都維持為綠色黑板上的白色粉筆畫。教室背景、課桌、椅子和海報完全靜止且保持不變。鏡頭不移動。

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
