And I mean it's literally touching. The guy actually lets fans touch his face by bending forward on stage, allowing them to reach up and caress and/or hold his face with their hands. It's a very brief yet intimate moment between the star and his fans, and I'm sure the fans are touched by the allowance of touching.
Needless to say, some fans grow too excited and even inflict unintentional, minor cuts on G-Dragon's body, specifically on his arms. You can see him applying medicine to the wounds below. Despite these hazards, it seems G-Dragon will continue letting his fans touch him whenever he feels up for it!
It's a nice way for him to feel and physically get close to fans, and G-Dragon is such brave soul for allowing all those hands to get near his face.
