My main protagonist has a complicated history and relationship with her family and I'm having trouble deciding how to reveal this in the story. You can't just dump it on the reader in one paragraph but it is not exactly a mystery that should be solved slowly either. In a lot of stories, the main characters have a normal life so not much is to be said about it. The characters with gritty backgrounds are characters that the MC interacts with. I don't want to start at the beginning of my character's story, since it will slow down the plot and is unnecessary. It shows how she first meets the group she is with but it is unimportant how they met. So how do you best reveal aspects of the MC's history? And how do you best explain the relationships they have with the other characters?
