可乐互动叙事（ByteDance Seed 官方 I2V 范例） prompt

The character in the painting looks guilty, darting glances left and right before leaning out of the picture frame. Very swiftly, they extend a hand outside the frame, grab a cola, take a sip, and reveal a look of deep satisfaction. Hearing footsteps approach, the character hastily puts the cola back just as a Western cowboy walks by and picks it up. The ending shot pushes in on a top-lit close-up of the cola against a pure black background, with artistic subtitles and a voiceover appearing at the bottom: 'Yikou Cola, an absolute must-try!' Constraints: keep character identity stable, no watermark beyond the deliberate caption.
