Kim Jong Kook and Yoo Jae Suk promoted themselves as a 'wedding package'?

Yoo Jae Suk and Kim Jong Kook revealed that they previously promoted themselves as a "wedding package".

On the November 1st episode of 'Happy Together', Yoo Jae Suk revealed, "Kim Jong Kook and I went around like we were part of a 'wedding package'." When the others expressed their curiosity, he explained, "Whenever I acted as the event host, Kim Jong Kook would sing the congratulatory songs."

Kim Jong Kook agreed and reminisced about Kang Ho Dong's marriage. He shared, "I was told that I would be the only one singing at Kang Ho Dong's marriage, so I figured the song should be calm. I wanted it to be meaningful, so I sang 'Pledge�of Love', and Kang Ho Dong complained that it was too simple. I guess he didn't like it."
