Fans might have been disappointed with the outcome of this week's Music Bank K-Chart a few days ago, but if f(x) continues to put on spot-on performances like today, it's hard to complain and be disappointed. These girls are such a joy to watch because they make their performances seem so effortless to do. They definitely know how to demonstrate the catchy portions of their dance for NU ABO, such as the touch cheek, the NaNaNa, and of course Krystal's shirt lifts. Don't deny it! This song definitely grows on you in several ways. Enjoy the show! http://www.youtube.com/watch?v=Ly8_AZD-AQk
