[Style] Original experimental visual effects, golden-hour realism, elegant particle transformation, quiet emotional tone.
[00:00-00:05] In a fictional town square, every person stands still while their shadows slowly detach from their feet and stretch toward the same alley.
[00:05-00:10] The shadows climb walls and merge into a flowing black river that moves against the direction of sunlight. People watch, but their bodies cast no new shadows.
[00:10-00:13] The river rises into the air and separates into thousands of dark bird-like silhouettes, circling above the rooftops.
[00:13-00:15] The silhouettes dive back to the ground at sunset, but each shadow returns to a different person. Everyone looks down at the unfamiliar pose beneath them.
