Perhaps the best thing in 'Goodbye Mr. Black' is Moon Chae Won and Song Jae Rim's chemistry - and Lee Jin Wook's general hotness, of course.

Two behind-the-scenes videos for the drama were dropped by MBC today, one showing how the 'evil' Kim Kang Woo can be a prankster when the cameras aren't rolling and the other showing that Moon Chae Won and Song Jae Rim are just as cute off camera as on.

Check out the two cute videos above! �Are you enjoying the drama?
