Honestly, everybody around tumblr has seen and heard about the rumor but i haven't found anything anywhere else... Personally, I don't think that will happen. I don't think it's true... I think it blew out of proportions around tumblr.

I doubt they are a couple, although being Jun so secretive, nothing would surprise me at this point. If he has somebody, that he might, as happy as he is lately, I doubt is Mao chan.

And again, as secretive and private Jun is, I always think that he could manage getting married and keep it a secret :P

I do think that Jun may be the first one tying the knot... but I don't think we will learn when beforehand...

Just my two cents...
