JYJ's Junsu as well as B2ST's Doojoon and Yoseob were snapped visiting musical actor Park Gun Hyung backstage. Park Gun Hyung is currently starring in the musical 'Zorro', and the three idols decided to visit the theater to congratulate him. The four became good friends, as they're all members of the celebrity soccer club, 'FC MEN'. Junsu, Doojoon, and Yoseob were said to have enjoyed 'Zorro' immensely, as they laughed and clapped all throughout the show. They commented, "It was fun because Park Gun Hyung plays a part that's similar to himself; we were impressed at how he had to go through dangerous segments because it seems like it required a lot of effort." Park Gun Hyung thanked his friends for coming to see his musical despite their busy schedules. 'Zorro' is currently playing at Seoul's Blue Square until January 15th, 2012.
