I don't personally ship Drarry because I ship Dramione, but I have read a Drarry fanfiction which was interesting to read. I think that it would of been such a plot twist to the whole story if Harry would of ended up with Draco, it would also show that people can change for the better. I think that Draco did have a tiny crush on Harry, he visited him on the train every year and was always talking about him. I think that Draco was also a bit jealous of Harry because most people looked after him and nobody looked after Draco and that's why he was pulled into the Death Eater/Voldemort thing, because no one was there to save him.
