Yay, another OW fan! There is a definite shortage of good OW fics. I always seem to find a lot of slash when I go searching. But if Oliver were gay, well... I'd be really depressed lol.
Very well written. I think you captured Oliver's competitive streak and how hard he takes a loss very well. Good characterization of Katie, as well. I don't portray her so nicely in my own fic lol.
