Short video, 15 seconds, heartwarming and dramatic style, 4K resolution, 60fps, cinematic lighting. Scene 1: A 3-year-old child wearing a red jacket runs to the edge of a suburban road, chasing a butterfly, unaware of a speeding bicycle approaching fast. Scene 2: A golden retriever puppy suddenly dashes out from the grass beside the road, barks loudly, and pounces on the child, pushing the child to the safe grass in the nick of time. Scene 3: The bicycle whizzes past the original position of the child, the driver looks back in shock. Scene 4: The child cries softly, the puppy licks the child's cheek to comfort him, then sits beside the child and wags its tail, waiting for the adult to come. No text overlay, background sound: the child's laughter at first, then the puppy's bark, the bicycle's bell, and finally soft, warm background music.
