Singer Kim Jong Kook shared that his mind was blown when he first found out that HaHa was going to get married.

In a recent interview he had before the release of his new album, he said, "HaHa and I used to share our life problems together including the issue of marriage. But when that child told me he was going to get married I experienced mental collapse."

He continued, "I am really jealous. More than the fact that he is getting married, I am jealous that he was able to come to the decision of getting married."

Kim Jong Kook, who also stars with�Yoo Jae Suk, Ji Suk Jin, and others on SBS's 'Running Man', also shared the stories and advice he has received from his castmates on the topic of marriage. "The hyungs who are married have different takes on marriage," he said.

"Yoo Jae Suk hyung tells me that I am not a guy who really goes out and parties too much so just hurry up and get married. He gave me this advice saying that I will then be able to lead a more stable life. But Ji Suk Jin hyung tells me that if I want to get married, it is better to push it off as long as I can," bringing everyone to laughter.
