Kwanghee shared a funny story involving Park Myung Soo. 

On the February 21 airing of KBS2 'Happy Together 4,' Kwanghee shared a story involving Park Myung Soo while on the talk about 'Infinity Challenge.' 

Kwanghee said, "Myung Soo hyung loves it when I surprise him at his work so one time, I went to surprise him while he was DJ-ing."

He continued, "I was wearing a hat and had my face fully covered. I crawled toward the DJ booth where Myung Soo hyung was. I was right in front of him but then Myung Soo hyung's manager and security blocked me. They were kicking and holding me back so I was so surprised. I was eventually set free after they saw my face later."
