Yoon Do Hyun and Girls' Generation's Sooyoung have transformed into each other, fulfilling a pledge they had made.

Yoon Do Hyun and Sooyoung pledged on the September 5th broadcast of SBS's 'One Night of TV Entertainment' that if 'One Night of TV Entertainment' ranked first on search rankings, Yoon Do Hyun would transform into a Girls' Generation member, while Sooyoung would transform into a rocker for the opening of the next broadcast.

Their new images will be shown on the September 12th broadcast of 'One Night of TV Entertainment' at 8:55 PM KST, so make sure to check it out!
