Seo Kang Jun's cameo appearance in Entertainer.

Entertainer drama has its latest addition of cameo appearance recently. Actor Seo Kang Jun appeared as a cameo in the drama as Kyle's (Gong Myung) best friend Lee Sang Won. Sang Won was once a foe and bestie to Kyle at Juilliard until not long ago the two of them became rivals.

Surprisingly Sang Won took the effort to meet up with Kyle and confesses that he wants to meet up with him and missed him too. That made Kyle teared up that Sang Won still thinks of him. In fact Sang Won helped the new band Entertainer to regain fame by appearing to play together with them on an event. Awww...how sweet of him.

Entertainer is headed by Ji Sung, Chae Jung Ahn, Girl's Day Hyeri and CN Blue's Kang Min Hyuk.

In real life Seo Kang Jun and Gong Myung are from the group 5urprise launched by Fantagio. These two men have branched out their career from singing to acting as well.
