ZE:A's�Hyungsik, Siwan, and Kwanghee appeared on SBS's 'Healing Camp' on August 10 for a fun time both entertaining the audience and covering deep topics - and of course attacking one another with teases.

Kwanghee pointed out how greasy Hyungsik was, explaining that he would be playful with the members before a signing event and then once the doors opened, he would completely change and start throwing greasy winks at their fans.

In return, Hyungsik claimed Kwanghee had changed after joining 'Infinity Challenge,' elaborating, "Once, I had a meal outing with the dream team, but a phone call came from Kwanghee. �In response to Kwanghee's 'Let's go watch a movie,' I said, 'I can't because I'm on my way to a company outing.' �Then he responded with, 'Hyungsik. I'm Hwang Kwanghee... don't you see me on TV?,'" making everyone burst into laughter. �

Also on this day, Kwanghee said upon seeing Siwan, "It's been such a long time. �I see Hyungsik often." �As he seemed upset, Siwan said, "I support Kwanghee's life, but if I meet up with Kwanghee more than once a week, it feels like my energy is being squeezed out. �I don't meet him before I have filming."

Kwanghee does have a ton of energy!
