Our society is basically judging by relevance now....*sighs*
I support Kikyou and Inuyasha as the past pairing, and still somewhat do with the current relationship.
But since Kikyou has already accepted the fact that Inuyasha does like Kagome and hasn't came between them yet, I'd support the Inu/Kag pairing, after they prove to me how they can see each other without suppressing and abusing the benefit of going to the future/past.
