I need to know (Drarry)

When Harry goes to a fortune teller at a fun fair he is told his life could've been very different and better if he had made a different decision when he was younger (inspired by a beautiful youtube video by paquim)

I do NOT own any of these characters they all belong to J.K Rowling

In every one of these chapters there will be scenes and lines directly from the movies, I obviously do NOT own these lines, I just like to keep the same rough parts with some other details in there.
