It's true. I've thought about that a few times over the last couple days as I've been enjoying it. I mean, part of why I like the fic so much is that it reminds me of couples I know or stories I've heard of people who fell in love through fandom, but they've all been women (including one woman who thought the BNF she was reading was a guy but when they met up she turned out to be a woman too). I like stories about girls who write fanfic and I've even written fic about Gwen and Morgana writing it. But I know a story about girls would never have the same kind of general appeal that that Arthur/Merlin one does, and I'm not sure if even I would enjoy it as much as I have this fic. There is something about boys being insecure and angsty, and something about boys being lovey-dovey once they get together. I still find it irresistible.
