On October 12 airing of SBS 'Healing Camp,' actor Joo Won guested on the show where he talked about the burden of taking on main roles as well as the physical toll that he's endured through filming.

When asked about being burdened, Joo Won said, "Being burdened is inevitable. I think its natural to feel burdened as the lead role since the production costs are no joke."�

He continued, "I don't like to burden anyone so no matter what happens, I try to tolerate it. If I try, I can understand anything. With time, it can happen."

MC Kim Jae Dong then asked, "When do you feel the most disappointed?" to which Joo Won answered as his eyes started to fill with tears,�"I blow up when people don't recognize how much of an effort I'm making."�

He continued,�"I was filming for nearly three months and for two months I couldn't sleep and felt like a crazy person. I was physically... I thought then that I would die like this. I had an IV in my arm while traveling. I just lived like that. Then, I thought, 'Is it okay to just tolerate this?'

In the past, I would think what's good is good. But then I thought that people were just like this because I kept tolerating. So I blew up. But the problem was when I blew up, when I felt that disappointment, I ran to my car and cried."�
