Shin Hye Sung recently guested on jTBC's 19+ talk show "Witch Hunt" and shared some of the untold story of Shinhwa in the past.
During the show on May 30th, Sung Si Kyung asked, "I heard that when you used to stay in the dorm together you didn't wear any clothes and you guys know about each other's bodies very well".
According to a report on Dkpopnews, Shin Hye Sung replied, "We once had a dance battle and all the members were naked.
"It's not just a normal dance battle but we also did break dance. There was a person who even wore a helmet then he did the head spin", which made everyone burst in laughter over his story.
Yoo Se Yoon commented, "Then wasn't it like a helicopter?" while raising his arm and made it look like the helicopter rotor and made everyone laugh with his gag joke.
