On the December 5th episode of SBS's "Running Man," Yoo Jae Suk discussed a recent chat he had with actress Yoon Eun Hye, which was broadcast live.

One of the missions in this episode required the participants to talk about someone in front of them while they were wearing headsets. It was Yoo Jae Suk who pulled Yoon Eun Hye into the conversation when it was Kim Jong Kook's time to wear headphones. The old "love line" between Yoon Eun Hye and Kim Jong Kook on "X-Man," as well as his more recent "love line" with Song Ji Hyo on the drama "Running Man," is a source of much amusement for Kim Jong Kook.

Yoo Jae Suk remarked, "I received a text from Eun Hye," as Kim Jong Kook was listening through headphones. "I hesitated whether or not I should call her, but in the end, I dialed her phone number." The members checked to see if Kim Jong Kook could hear them, and Song Ji Hyo questioned him, "Do you like me or do you like Yoon Eun Hye?" Kim Jong Kook replied, "I like both of them."

Early in the game, Kim Jong Kook interrupted the music, overhearing their entire conversation, and told Yoo Jae Suk, "Don't talk about this things on television."

Rather than responding directly to his reprimand, Yoo Jae Suk pretended he was having problems in the military and stated, "I will erase her phone number, sir." Since then, sir, we haven't had a chance to speak. I was relieved to be able to speak with her for the first time in a long time, so we talked about a variety of topics. "I apologized to her, and she assured me that everything was fine, sir."
