Change is inevitable: Serious looking Kim Hyun Joong

This set of pictures were taken during the filming of Mischievous Kiss. Now we can see this side of him in the office. Seems like he was too serious about his work. In this angle, I see Hyun Joong in a professional pose. So this is what he looks like if he was not an artist and was working in an office. Naaah... I prefer you acting or singing on stage with your SS501 brothers. ^^
