Jung II-woo had a cameo appearance in episode one as Lee Yoon-ho! I imagine that for fans that had not seen him in a long time it must have felt like water after a walk in the desert! How did he look? Well take a look below.
First is the video of Episode 1. Jung II-woo appears at 4:06 until about 8:30. Cr. MBC
