Yoon Eun Hye and Nichkhun get down in a club. Why? For the newest Cass CF, the same brand Sandara Park filmed with Lee Min Ho. The two grind it up on the dance floor and prove they are one good looking couple. And judging from the still shots, it seems like there's going to be some interesting drama in this one, just like there was for Dara and Lee Min Ho. The Cass CF music video featuring Dara and Lee Min Ho gained a lot of love and attention - we're sure this one will as well. Yoon Eun Hye is sporting a sexy low cut club dress and Nichkhun is wearing some kind of sparkly jacket, which Yoon Eun Hye should've been rocking instead. Check back soon, the music video will be released in early Jan 2010.
