SEE ALSO: 'Running Man' starts a RT movement on Twitter to get Yoon Eun Hye to appear on the show

PD Lim Hyung Taek told Sports DongA on the 10th, "We also want Yoon Eun Hye to appear on 'Running Man'... We asked Yoon Eun Hye to appear [on 'Running Man' multiple times before, but she rejected it each time... It seemed she felt that it was burdensome if she doesn't have a particular reason for appearing on the show... If the opportunity presents itself, we hope that she can appear."

He also told another media outlet Star News, "We have asked her reps recently for her to make a guest appearance, and they said if a good opportunity presents itself then she'll film with us... However, we haven't been able to confirm any specific details or dates... We have been getting so many requests on our homepage from domestic and overseas fans who have asked for Yoon Eun Hye to appear. It seems they're showing a lot of interest thanks to her good ties with the 'Running Man' members from 'X-Man' days... We think we'll receive a lot of great feedback with her appearance."

Meanwhile, SBS' tweet that asked Yoon Eun Hye to appear on 'Running Man' has already surpassed 34,000 RTs, three times more than its goal of 10,000 RTs.
