Have any of you heard of Vienna Teng? (If not, please check out her stuff; Vienna's music is absolutely gorgeous. She's a brilliant composer and her lyrics are pure poetry.) Anyway, I got into the FMA manga and Vienna Teng's music around the same time. When I first heard this particular song, I immediately thought of Ed and Winry's relationship in the manga...so of course I had to do something with it. (And whew, I had no idea an MMV could be so time-consuming!)
This could be seen as either romance or close friendship; whichever you prefer.
