Joon Won revealed that he was is unable to have time to sleep due to his recent ridiculous busy schedule consisting of filiming for his drama 'Bridal Mask' and '1 Night and 2 Days.'

On the 27th Joo Won mentioned during the 'Bridal Mask' open production "The drama filming is rotated by team A and team B. We film from the morning to night and stay up all night filming until the next morning. While the B team is in production ,I sleep for a little while and then stay up all night to film again. And then while I am filming mindlessly for the drama somehow I end up at the filming for '1 Night and 2 Days'." And revealed the busy tight schedule he is currently abiding by.

"I try sleeping in the midst of things but I only get to sleep 30 minutes a week so I feel like I'm having a out-of-body experience."

"But even though I don't get that much sleep whenever I come to film for the drama, I get this surge of power. I lost a lot of weight but I'm really putting my all into this drama."

Park Ki Woong also mentioned "I think this past week I haven't slept in a bed, I'm in the same situation as Joo Won so we talk a lot. We don't really think about our bodies but the fact that because we're so tired we might miss the important lines that we really need to boast up during a scene. We've become each others energy boosters!"
