They say this is Young K's true self as revealed by Wonpil~

It really touched me to hear Wonpil talk about Young K, whom he has watched for over 15 years. In particular, the part where he described him as an "icon of effort" and mentioned seeing him up close worrying and striving to fit in well on "Amazing Saturday" really resonated with me. I think another charm of Young K is that he possesses a sincerity that is recognized by those around him, not just what he shows on stage.
