I think the reason why this one is considered good is because so many Sniper/Spy stories are written... rather badly...
It's a typical romance, Sniper discovers that he is gay and attracted to Spy, Spy breaks up with his little cauliflower and reveals his attraction for Sniper, they work through some inevitable problems, and voila, romance.
The author has published the same story for profit and changed the names, removing mentions of TF 2
. I think that if the author didn't mention it, no one would be the wiser.
It's not bad, it just reads as a little generic. With French and Australian accents. Overall...
It Could Be Worse
(Yes, I had to insert a lame Title Drop)
