On Wednesday of MBC "Radio Star," 2AM Changmin guest starred along with music stars Nam Kyung Joo, Jung Sung Hwa, and Lee Min Ho.

On this day, Changmin shared about Jo Kwon's confession on "Strong Heart" that he was disappointed that his fellow members didn't show up for his solo debut music video shooting. He expressed, "That day all our members had different agendas."

He added, "We heard that all of the 2PM Wooyoung's members came for his music video shooting. As soon as we heard it we bought a bunch of coke and hamburgers and ran to where he was. We got on our knees and begged him to forgive us."

MC Yoon Jong Shin commented, "No one came to Changmin's performance. Isn't it equal?" Changmin replied," I told them not to come because I was too nervous."
