The K2's producer's comments about Girls' Generation Yoona's acting

Kwak Jung Hwan (producer of The K2)

I think Ji Chang Wook and Yoona have a lot of potential. I can't believe they've been caught up in controversy due to their lack of acting ability. They're putting everything into the drama, and I'm sure people will speak very highly of them at the end of the drama. Actually, Yoona never cares about her appearance during filming. She is a willing horse, and she even got a bruise on her knee while filming one of the scenes of the drama. But she just told me, "I'm very happy that I can try something new in the drama."
