Wheesung said, "I get severely nervous when I'm on stage. It's very serious to the point where people wouldn't understand. My fans know of this [as well]. And sometimes the up and down is really severe, and it even gets hard for me to breathe. I think of how great it would be to sing without concerning myself about the cameras."
