'Aggressive Joong Ki' reflected on filming his first episode with the cast of SBS's "Running Man" in a recent interview with Newsen. "When I first began filming for 'Running Man,' I was severely nervous because it was my first time on a variety show. I never had any idea what to do and I barely got any sleep the night before recordings," he expressed. WIth a laugh, he continued, "But with every new recording, I became closer with the members, and now it doesn't even feel like I'm recording, it just feels like I'm here to play." At the mention of his teamwork with the other members, he stated, "If we weren't close to one another, the show would be awkward. We chat and joke around during break, and I think that energy carries over to the show in creating a lot of fun and natural cuts." Whether or not the camera is rolling, he revealed, laughter is unending on the set of the show. Producers of the show commented, "He's really aggressive. Despite it being his first variety show appearance, he adjusted quickly, which surprised all of us. He's basically the maknae of the 'Running Man' members, and really does receive a lot of love from the cast and the crew for it. The few times where he's lacking is actually charming to us. Not only is he close with his cast members, but all of the staff members as well." Source: Newsen via Nate
