On the radio show, Kikwang requested Rain's debut song "Bad Guy" to be played, and commented, "The intro to Rain's "Bad Guy" is so cool. It was so cool even from a guy's perspective. I was blown away when I saw the performance as a kid. It was just perfect!"
He went on to say, "The track was from 2002 and I was in junior high school during that time. I would like to perform together on stage with Rain sunbaenim someday," he added, raving about Rain's charismatic presentation.
When Kikwang first debuted as AJ with "Dancing Shoes" back in 2009, a lot of people compared him to Rain, so you can see that the singer had a lot of influence on him.
