As Kim Hyun Joong and Jin Se Yeon's onscreen romance starts to blossom, it appears they've gotten closer and more comfortable with each other, especially apparently when it comes to skinship! This time, it wasn't the typical kiss or holding of hands, but a pat on the butt with Jin Se Yeon patting Kim Hyun Joong like a baby while he can't help but smile. 

Make sure to catch more of the two on 'Generation of Youth' every Wednesday and Thursday!
