Crime Suspense Beverage Spill

20-second, 16:9 photorealistic live-action crime-suspense scene, one continuous take, fixed low-angle 35-50mm camera, cool-gray modern beverage area, shallow depth of field, no BGM. 0-7s: B approaches the dispenser, places a transparent cup underneath, and fills it with orange-yellow beverage. The machine overfills; liquid spills over the rim, down the cup and onto her fingers and metal tray. B gives only a tiny annoyed reaction. 7-12s: A black handgun slowly enters from B's right rear. B notices it through peripheral vision and instantly freezes. No screaming or exaggerated reaction. 12-15s: A comes gradually into focus behind B, wearing her black outfit with long straight black hair and gold earrings. She calmly says, "You know too much." 15-18s | FINAL REVERSAL: Instead of surrendering, B suddenly swings the filled cup backward and throws the orange beverage directly into A's face. The liquid clearly hits A's face and hair, splashing realistically. B must NOT throw it into her own face. 18-20s: A stands stunned, orange beverage dripping from her face and hair, still holding the handgun. B remains facing forward with a restrained, almost deadpan expression. Brief awkward silence, then immediate cut. Sound: only realistic footsteps, dispenser hum, liquid flow, cup movement, splash, fabric rustle, and dialogue. No music, gunshot, chambering sound, horror effects, or exaggerated reactions.
