look at how they performed they don't really seemed to be enjoying, ever since the beginning nobody was smiling. They' don't seemed to be cheerful, energetic and playful they're not in their usual selves not like in their previous performances like how we see them in their concert, TV appearances, etc. but for the sake of the fans, like what we always say :the show must go on!", This is very unusual to me. Girls' Generation wouldn't be Girls' Generation when there is missing one. I'm still hoping for a miracle to come!
