Cha Tae Hyun discussed the 'Dragon Club', which Kim Jong Kook is a part of, saying, "We went on a 5-day trip recently, and I started getting tired on day 3. I wanted to go home, and I missed my kids. There was nothing more to say either. We kept talking about the same thing, and it's not like we really talked either." They also said the "face" of the group is actor Jang Hyuk.
As for the relationship expert of the group, Cha Tae Hyun called out Kim Jong Kook, saying, "I always say it's Kim Jong Kook. I feel like he has a girlfriend in America for sure. It doesn't make sense that he would travel with his mother. He definitely has one."
