My Favorite Coupling in Gundam Wing, or one of my Favorites.
I love the 3x4 Coupling (Quatre and Trowa). It's a fun coupling, and it always works out in stories if you think about it. Not only that, but let's not forget, Bishounen makes Anime go round, hehe. (But that's not the only reason why I watch Anime, although it could work if Anime has no redeemiing qualities)
