The Weight of What-If?

My first fanfic so don't hate. I'm trying to follow JK's basic storyline so it seems similar to the books/ movies, but with some differences to make Drarry happen.

Harry Potter thought the war was over. He was wrong. Nightmares haunt him, every corridor of Hogwarts feels like a graveyard, and the last person he wants noticing the cracks in his armor is Draco Malfoy. Enemies. Rivals. Roommates.
But when a spell accident drags them both into the past, the lines blur in ways neither expected. To survive, they'll have to face not just history, but each other-and the truth hidden beneath years of hatred.

I'll try and upload a chapter whenever I'm free and if people actually read it.
I literally have no idea what I'm doing so help me out. Comments are much appreciated! I don't know what votes are but I'm guessing it's a like button(?) so yeah, votes will help me post chapters faster too. Thanks y'all for choosing this.
