Who's that pretty lady giving Nichkhun a ride on her shoulders?

Last week, a behind the scenes video for 2PM's It's Skin CF was revealed on KBS Entertainment Relay. One of the ladies wearing a sky blue bikini and giving Nichkhun a ride on her shoulders caught the eye of many netizens and it was revealed that this pretty lady is 2006 Miss Korea 2nd runner-up Jang Yun Seo. Jang Yun Seo revealed that she was nervous giving him a ride around her neck, voicing concerns that she might fall and put a scratch on his pretty face. However, once the shooting started she stated that everything went smoothly. In 2006, Miss Korea went to Lee Honey (Miss Universe 3rd runner up), 1st runner up went to Sharon Park (no placement at Miss World) and 2nd runner up went to Jang Yun Seo who placed 2nd runner up at Miss International. Jang Yun Seo plans to debut as an actress soon and hopes that this CF is a stepping stone for her career.
