Who does Sora care for more

I'm assuming your asking who does Sora care for more between Kairi and Riku, well, it is more of an opinion.
I, personally, say Riku. Part of this is because he chooses to continue looking for Riku, rather than being with Kairi, or bringing Kairi along to find Riku. Though, perhaps he desn't want Kairi to get hurt, hwich is quiet a tossup.
The other part of why I say that is because I <3 yaoi, but lets not get into that (but feel free to talk to me about yaoi on my message board ^.^)
