On February 17, Kyuhyun started MBC's 'Radio Star' by apologizing to viewers as many netizens said they were disturbed by his comments towards Yang Se Hyung. The controversy started as Kyuhyun replied to Yang Se Hyung as he shared a story about the time he officiated Kyuhyun's friend's wedding, but did not get paid properly. Many netizens said that Kyuhyun was rude as he purposely tried to make Yang Se Hyung look bad. 

As a result, on this week's opening of the show, Kyuhyun said, "I am most worried for myself today. Today I hope I can survive without trouble," and also added, "I apologize for disturbing the viewers with my actions on last week's show. I was embarrassed of myself when I looked back at my actions." 

To this Kim Gu Ra added a funny comment as he said, "Kyuhyun was criticized badly for this. He is now really following my path." Throughout the show, the other MCs continued to make fun of Kyuhyun regarding this controversy.
