About the Forehead Touch
You know, this one from the special we are now crying at.
This is actually a famous pose that had been long used by Korean fashion designer Andre Kim. Being a world-famous designer, he was able to invite the hottest stars to come walk in his fashion catwalls, and usually at the end of the show, the male star and the female star will share in this pose, to signify love and conclusion.
The following people are all so freaking famous that I trust I don't HAVE to introduce them, but I will:
Kim Tae Hee and Song Seung Hun
Lee Da Hae and Jang Geun Suk
Kim Joon and Jang Nara (Jung Saem!)
Song Hye Gyo and Won Bin
P.S. It is known fact that the "Andre Kim pose" has to be placed as such that the woman is on the left and the man is on the right. So, regarding Woo Bin and Jong Suk's positions, I think I need not say more... >:D
