Heero and Duo?
Now here's a pairing that's had plenty of attention - just about every writer of GW yaoi fiction starts off with Heero and Duo. ^_~ Why? Well, for yaoi fans, there are plenty of subtle hints in the series and Endless Waltz to work with. ^_^ There are also several different directions a relationship between these two could go - sweet and loving, rough-and-tumble, co-dependent and abusive, or solidly shoring up each other's weaknesses. ^_^ Whatever your preference, I guarantee that there are quite a few fanfics out there to suit your taste. ^_^v
