Previously on October 31 episode of SBS' television show 'Running Man', Yu Jae Seok made one intriguing promise to the production team.

To this, Kim Jong-kook, who used to be in on-air love with Yoon Eun Hye years ago, responded, "You must be crazy."
But Yu Jae Seok continued anyway, "We really should show something that a lot of people want to see, and that's definitely what they want. Wait and see. I'll make it happen next year, okay?"

The agency said, "Our staff and Yoon Eun Hye are all interestingly reading the articles about her being mentioned on 'Running Man'."
They continued, "'Running Man' production team never reached us for Yoon Eun Hye's official invitation yet though."

After reading the agency's response, fans became extremely thrilled.
