Although Kim Hyun Joong has a busy schedule, �fans were surprised to see him with a very tired face, especially on television!

Netizens have been going crazy over several snapshots from a recent episode of MBC's Playful Kiss. In the snapshots, the usually glowing face of Hyun Joong has been replaced by dull eyes, dark circles, and a slight mustache. A few comments that were made about his "changed appearance" stated, "The drama recording must be very hard. You even grew a mustache.", "He seems sleepy and super tired.", and "Kim Hyun Joong fighting!" On another note, don't the pictures make him look like a total copy of Bae Yong Jun?
