Love isn't finding a perfect person. Well, I don't have many obscure/hard to find pairings and I actually have to stop to think about this... Eto... Some of these aren't necessarily, yaoi, but they're all that I can think of. Sorry!
Naruto:
1) ShisuiIta-How come so few people ponder Shisui's role in Itachi's life??? ~cries~ There's so much potential there!
2) (My OTCP) ItaKyuu!human--I'll admit, I can find these two in an AU SasuNaru/NaruSasu fic, but when I try to find them in a fic where they're the main focus couple I can't find diddly squat! I don't understand it-these two are so awesome! cry
3) KonoHana--yeah, het. sweatdrop I've tried looking, but there's nothing.
Others:
4) Yami Yugi x Bakura--I'm not into YuGiOh so much anymore, but when I was there was a massage shortage in this couple. But-But-They're so cute! xd
5) (x-over couple #1 & half way het/yaoi--YYH/SM) KuramaxYaten--The only fic that I could find was the one by Sonya-chan. And she doesn't write anymore! crying
6) (goes hand in hand with the couple above) HieixMakoto--So cute. Sonya-chan's fault. She outdid herself with these two couples... And now I can't see Kurama or Hiei with anyone else! ~bursts into tears~
It's seeing an imperfect person perfectly.
