There could be a character who discovers that their shadow has a life of its own. This character would be the main focus of the story.

Or perhaps there are other characters who are also experiencing similar shadow - related phenomena, and they all come together to figure out the mystery behind it.

However, it's likely that there is a central character, maybe a person who is haunted or followed by their shadow in a more than literal sense.

For instance, a friend might comment on how the main character seems to be acting differently when their shadow behaves oddly.
