Mike's letter for Will | "Dear Will..."

So basically, this is a popular theory in the Byler fandom, that Mike has an unsent letter to Will somewhere. If you're confused about the beginning and the ending of this edit, it's basically just an idea of how season 5 could end (in a bad way). Both Will and Mike died in the war, and while going through their things Joyce finds this letter in Will's clothes. Mike gave it to him right before they both died. Will never got to know how Mike felt about him, only El got to know... (I have to make it clear that this isn't something I want lol, this would be really bad but I live for the angst, sooo...)
Also, BIG thanks to ‪@lesbianmindflayer‬ for this wonderful voiceover.
