That was when Yu Jae Seok said, "It's not just Kim Jong-kook. He's the same with Zo In Sung. He even went with him for a health checkup to a clinic."
Lee Kwang Soo awkwardly laughed commented, "Why are you telling everybody about that now? I went to get my body checked up as well."

Lee Kwang Soo said, "What are you talking about? It's not like I was free there! I was busy!"
Ji Suk Jin refused to listen to his words, and said, "So, did he pay for you as you did all that for him?"
Lee Kwang Soo suddenly went silent for a second, and answered, "He actually did. He paid for my health checkup, but...", making everyone laugh.
