I actually really don't get into yaoi type stuff since most of it just seems like throwing two random men together for the sake of fapping, but Cloud and Zack had a really good friendship as their foundation.
That's the big thing for me; there has to be a foundation for the two characters to even be together in the first place. Cloud and Zack have that where as most other yaoi pairings I've seen don't.
And yeah maybe I'm old fashioned but that's just how I see it. I need to actually be able to believe that the characters have genuine feelings for each other.
Yaoi&Shonen Ai are love. <3 I'm like Ten in the sense that I don't like throwing two random guys together just for the sake of them screwing. Sure, I like plenty of crack pairings, but I always have a story of how it could work thought up in my mind. =) I like my pairings to make sense, and I'm more into the love factor than the "OMG HAWT SMEX" factor, as hot as that smex may be. ::
AND CLACK IS CANON. PROOF IS PROOF PEOPLE, IT'S SHOWN RIGHT THERE IN TENNY'S SIG...
And what else would he be doing in the mansion? If Clack was canon, Clotis and Cleriths would have to stop arguing, and all the yaoi fangirls of the world would scream with glee. Happiness to all!
