JAESU to me, all the boys are extremely close and great friends. it's just that some pairings are more understated than others. (for me, the only other pairing that is even more subtle with their public affections than jaesu will be HOMIN) but not seeing as much jaesu does not mean that they are not close. you don't live six years together and not develop a bond with each other. jaesu are both very talented. yet instead of being competitive, they are very mutual about their admiration for each other in singing, in dancing, etc. and even though their PDAs are not showy, it is the little handshakes, pats on the thighs and the way jaejoong will tease junsu that tells you just how close they are with each other.
sometimes when the jaesuho sit together on the couch, the yunjae fans spazzing about the whole yunjae vs jaesu distance on the couch kinda overshadows the latter....

but nobody can srsly take this to mean that jaesu is not as affectionate a pairing as any other, yes?
I agree with most of what you said. Jaesu are very close, they're just not as open in public. Luckily, they're starting to show their friendship more often on film now. And fortunately, HoMin has been getting more public lately, as well. :-)
But it wasn't just YunJae fans spazzing about the Yunjae-Jaesu gap. Yoosu fans were also saying that Junsu sits so far away from Jae so that Yoochun doesn't get jealous. Even some Jaesu fans were saying that Junsu and Jae sit so far apart because of sexual tension. LOL. ALL the pairings have fans that read into things too much. Yunjae fans aren't always the sole offenders. Not saying you in particular, but there's been a lot of Yunjae stigma lately and it sometimes gets annoying. I know that that couple has a high amount of overzealous and somewhat crazy fans, but not all the fans are like that. I've also seen a high amount of insane fans in the Yoosu, Jaemin, Hosu, MinSu, and even 2U couplings. I'm a fan of all the pairings, but I know people who don't like some of the couples, hell, they even sometimes seem to have a personal vendetta towards the couples they hate. (Which I think that later boils down to those people strongly disliking one or more of the members involved in that couple, but that's besides the point.) If people don't like a pairing they just don't have to bring it up. (Once again, not saying this necessarily to you. ^^)

Request:Does anyone know where I can watch the video where the group was on a music program and the girls (I think some of the girls were from Perfume) were making fun of Jae for being vain and using too many emoticons?
Also, do you know when this was broadcasted?
