Kim Jong Kook and Haha hosted a Naver V Live broadcast titled Big Picture Kim Jong Kook and Hahas Lying Down Rooftop Live on September 13.
During their conversation, Kim Jong Kook brought up a surprising story behind the success of his song One Man. Kim Jong Kook said, Before One Man was released, I rested from the scene for a bit. That was when the music [scene] was becoming digitalized, but since I didnt know anything about it and [companies] didnt say anything, I didnt sign any contracts [regarding digital sales]. He added, I didnt even make 10 won (approximately $0.0009) from One Man.'
