haha, that was a great episode of SGB.
As for Gyuri, this is the thing about her which I love the most. In fact, its not merely just self confidence, I'm sure a lot of idols have confidence in their own appearance, but in Gyuri's case she expresses this self confidence so regularly and freely, and this is definitely something that most idols don't do. But I guess this is what makes Gyuri stand out.
