s01-aEdit this photographic storyboard frame. Replace ALL visible adult party guests with East Asian adults with natural Korean/Taiwanese appearance, preserving each person's original pose, clothing, relative size and placement, the exact off-center handheld vertical phone framing, room, cream counter, pink cake with red hearts, background depth and warm lighting. Main birthday woman: East Asian woman in her late twenties, straight shoulder-length dark brown hair parted centrally, natural face, same black V-neck long-sleeve sheer top and gold necklace, leaning low laughing just ABOVE the intact cake. Background right woman same white off-shoulder top and grey jeans; background woman same black camisole and phone. Hands near her head match East Asian guests. Preserve cake untouched with red hearts, same cake scale/perspective. No man holding plate is visible yet. Plain candid phone-video still, realistic imperfect skin, NOT glossy advertisement. Keep 9:16. No text.
s01-bEdit image1 into the very next key moment after image2. Use the SAME East Asian women, dark hair, black sheer V-neck clothing and gold necklace, Korean/Taiwanese appearance from image2, not the Western identities in image1. Preserve image1 exact cake-face-contact pose: guests hands lowering her head, nose and cheeks touching pink cake frosting, displaced frosting. Background guests in same white top/greyjeans and black camisole, all East Asian. Same cake with red hearts, same counter, plain warm phone camera tone, same off-center 9:16 handheld framing. Image1 supplies action/composition only, image2 supplies cast/hair/skin and room consistency. No text, no tears, candid realism.
s01-cEdit image1 as final key moment of the same party in image2. Replace the Western birthday woman with EXACT same East Asian dark-haired woman in image2, same black sheer long-sleeve top and necklace. Use same East Asian guests from image2. Image1 defines action/composition: woman has pink frosting smashed on mouth and nose, eyes laughing, holds the damaged WHOLE pink red-heart cake in BOTH hands angled sideways about to swing it, cake crumbs and pink cream flying over counter, damaged cake no longer edible. Main birthday woman's shoulder-length hair remains dark brown, not blonde. Preserve close wide-angle handheld vertical9:16 camera position, room and party background. Candid phone video look, no text.
Video prompt
One continuous candid vertical phone video at a birthday party, exactly the East Asian women, dark hair, clothing, room, counter and pink red-heart cake in the supplied frames. The first frame is the intact cake before a prank; the last frame is the SAME damaged cake held sideways by the SAME birthday woman, not a replacement cake. Show physically connected action, real normal speed, warm domestic light, imperfect phone handheld motion only, no cut or zoom. No man with an empty plate appears in this shot. From 0.00s to 0.35s the smiling woman leans above the intact cake and friends hands approach her head. From 0.35s to 1.20s friends gently press her face into the soft cake frosting; at 1.20s her cheeks and nose visibly touch the compressed cake top. From 1.20s to 2.00s the hands release and she lifts her face, pink cream stuck around her mouth and nose. From 2.00s to 3.40s she grasps the same cake with both hands and lifts it off the counter. From 3.40s to 4.60s she swings the damaged whole cake sideways playfully; at 4.60s cream and cake crumbs scatter and there is no clean cake left to serve. From 4.60s to 5.60s keep the messy cake in both her hands as friends recoil and laugh. From 5.60s to 6.00s the laughter and small live movements continue at the final damaged-cake state. Cheerful adult party laughter, soft cake squish and room sound, no music, no dialogue or narrator. No captions, text, new cake, extra limbs, tears, injury or slow motion.

Editing
Hard-cut to a fixed close crop for the last replay. Slow it from 0.75× toward 0.45×, lowering the laugh’s pitch with it. Soften focus before the small agi.geek label appears. Keep the first laugh at normal speed.
