Title is basic bc idk what to call this. I see this as more of an imagine or a short story unless someone can somehow stretch this out to an entire story lol.
Update: I've started reading 'Dear Michael'; it was uploaded before this and I didn't know about it when I had this idea. Oops. Check it out!
A fan gets the opportunity to send Michael some fan mail. They choose to do it in the form of a story. When the envelope only allows portions of the story to go at a time, the fan is forced to break it up into parts. One day when they take a long while in sending the next part, they get (either a visit from MJ or a letter back) when they thought he wasn't even really reading their story.
