It was in Blaine's point of view, until the end when you realised it was his fathers point of view.
I recall Blaine and his father having the same name and it was going through his life story. I think there was a red/golden haired boy named Robert? who Blaine/His father liked when he was younger.
I think it was on either here(Livejournal) or Fanfiction.net.
Sorry for the small amount of details, but I have a bad memory and the twist at the end is unlike any other fanfiction I've read. (If there are more please link me them)
