What to do when your story has no purpose?
Or at least no visible purpose. When I write stories, I find that I focus more on the characters themselves than the story. This leads to me making my characters as sad as I can [as many OC creators do-], and a butched story.
Now when I DO have a story, I feel like it serves no purpose. No lesson is learnt, no reward is given, its just a story for the sake of a story. For example, I currently have one that follows the premise of two science experiments who escape but get seperated, one goes on a rampage and doesn't remember the other and the other has to try and stop them and get them to remember them. To me, this is pretty bland and doesn't serve a purpose, or at least if it does, I don't think much can be done with it because of how little it allows.
For those who also felt this way, how did you get around or at least give your story a purpose if it didn't have one?
