And with KH there's the added factor that half the lead characters are children who are in the process of having their lives continuously shattered appart and yet still manage to remain strong and hopeful in the face of this. Hell, Riku's pretty much the antithesis type of Cloud's character type, the one who broke everything because he was too strong and is now in the process of trying to fix it.

(That said, Cloud is still my woobie and I appreciate him running around the KHverse being all pretty, even if I do wish he'd keep his mouth shut unless to snark. And getting pierced with phallic swords in AC. I am very shallow and they will always remain the pairing that made me 'get' the point of yaoi.)
