Young K also participated in the highlight challenge for CNBLUE's new song, Killer Joy, which is a hot topic these days. ㅎㅎ They seem to have a strong bond and are close because they are in the same band. They even have a video that has over 1 million views, so they must be really hot! Seeing Young K often appearing in idol challenges, I think he must be popular in the entertainment industry. ㅎㅎ
