@image1 is the exact character reference. Keep same face, hair, build, skin tone and exact clothing from @image1 every frame. Do not change face, hair, body, outfit or accessories. Style: vertical smartphone video, 9:16, 1080x1920, handheld at night. Raw mobile footage, realistic shake, motion blur, low-light noise, street-lamp lighting only. Maximum photorealism, like video filmed by a friend. Not cinematic. Duration: 10 seconds. Audio: night park ambience, traffic, wind, candle crackle. Climax: wooden “thunk”, loud cork POP, coca cola fizz, fireball “WHOOOMP”. Soft laughter at end. No speech, no music. Setting: ordinary nighttime city park. Dark sky, bare trees, warm lamps, dry ground, dead leaves, old wooden bench centered. Camera: handheld smartphone shot by unseen friend. Organic shake, waist-to-head framing. Sequence: 00:00-00:01.5: Empty bench. Person enters from right, smiling silently. Right hand holds coca cola bottle vertical, cork up, base down. Left hand carries small black cake on plate with tall burning candles. 00:01.5-00:03: They sit center bench, facing camera, smiling. Left hand extends cake to their left, right side of frame. Right hand holds coca cola opposite. Candles burn bright. 00:03-00:04: They shake coca cola vigorously with right hand. Cake stays steady. 00:04-00:05: Critical simultaneous action. Bottle stays vertical. Person swings bottle straight down and slams flat bottom onto bench seat on their right side, left side of frame. No sideways swing, no rotation. At same instant, they turn head left toward cake and blow flammable powder ACROSS candles. Powder ignites into huge realistic orange-yellow fireball, 1-1.5 m wide, bursting horizontally right like circus fire-breathing. 00:05-00:08.5: Extreme slow motion, 1/8 speed. Two effects together: 1. Cork shoots up. Powerful coca cola fountain erupts from bottle, 1.5-2 m tall, clear-white/golden foam and droplets. 2. Huge orange-yellow fireball blooms above black cake, with billowing flame, dark smoke, embers and natural sparks. No magic, fireworks or sparkles. Cake stays intact. Person keeps bottle vertical, cake extended, head turned left, mouth open mid-blow, eyes squinted. 00:08.5-00:10: Real time. Fireball fades into thin smoke. Coca cola droplets fall onto hair, shoulders, clothes and bench. Fountain weakens but keeps fizzing. Person relaxes, still holding bottle and cake, smiling and laughing softly at camera. Coca cola drips, faint smoke around face.
