South Korean singer and actor Kim Jong Kook's recent guest appearance on MBC's Radio Star was filled with fun and laughter when the show's host and close friend Cha Tae Hyun teased him to actress Han Ye Seul.

This comes after the Radio Star hosts Cha Tae Hyun, Kim Gook Jin, Kim Gura, and Yoon Jong Shin mentioned that Han Ye Seul named Kim Jong Kook as the closest to her ideal type of man during her guest appearance on SBS' My Ugly Duckling.

The Running Man member, however, did not take it seriously saying there were not a lot of options in the first place. Despite that, Cha Tae Hyun still encouraged a love line between Kim Jong Kook and Han Ye Seul and suggested they go out for some lunch or dinner date some time.

"I have seen her several times at the gym, and I have run into her in the United States as well," Kim Jong Kook explained to Radio Star hosts Cha Tae Hyun, Kim Gook Jin, Kim Gura, and Yoon Jong Shin, as quoted by Soompi. "Because we've seen each other a couple times here and there, that's probably why she picked me. I sent word to her that I was happy that a younger acquaintance of mine looked so favorably upon me," he added.

However, Cha Tae Hyun continued to poke fun at his close friend. He said Kim Jong Kook should meet the Madame Antoine: The Love Therapist actress to personally thank her for looking favorably of him, instead of just sending a word through a common friend.

For those who are unfamiliar, Cha Tae Hyun and Kim Jong Kook have been friends for more than 20 years and are better known as The Dragon Brothers along with actors Jang Hyuk (Windstruck), Hong Kyung Min and Hong Kyung In (Fantasy Tower). Despite their busy schedules, they always find time to bond regularly and to attend each other's major milestones whether it be personal or career ones.

Cha Tae Hyun, Kim Jong Kook, Jang Hyuk, Hong Kyung Min, and Hong Kyung In - who were all born in the year of the dragon - have also starred in a reality show together, Dragon Club: Overgrown Bromance. The show, which aired on KBS 2TV from October to December 2017, followed the group's adventure as they take a trip to Gangwon Province for six days and five nights.
