yes! totally! kazuXjun 4eva!!!

Possibly. I personally love Kaz/Jun but it really just depends on why.

Would imply he loved her in the first place, even it was not that kind of cliché-romantic-crush, he felt something special for her (and she for him...why never ask about, if she loved him? Or it seem obvious to everybody?) She faced him in a different way, than all other people he may met before. First one, who didn't have negative feelings right from the beginning, first one, who wanted to help and treated him nicer...in the end we don't know and the producers do everything to deny it, but nevermind, I believe in them :-)
