The identifier is a standard filename format generated by WhatsApp for videos received or sent on October 25, 2020 .
Because this is a private file naming convention, there is no public "story" or specific media content associated with it globally. It likely refers to a personal video—such as a family moment, a meme, or a clip shared in a private chat—that was saved to a device on that specific date.
If you are looking for a story that date or need a creative story written based on that filename, I can certainly help with that!
