Probably old news to everyone, but to me, I personally dunno if they ARE goin out with each other. So far from all the interviews I see, they both have feelings for one another and when the question pops up "Would you go out with him/her?" Their answer wouldn't be "No" anyways.
KJK was doing military service until May 23, 2008 (wiki), so the media with them two hasn't really much heated up or anything has happened. However, I would LOVE to see both of them together. They were like the best couple in X-Man, and it was funny when KJK was gonna dance for YEH.
A dream couple definitely, since a scandal about them was made and it heated up the media.
