Wai is a sound effect that's supposed to be cute...

What do you mean how do I know that they are gay. That's a pretty open question.

I don't buy into slash fiction, only Yaoi...

Your talking about Shonen-ai, I too see characters as being together and 'gay' has nothing to do with it. In my world 'gay' doesn't exist...It's just a by product of Christian teachings...
