f(x) strutted in funky hairstyles and outfits for another performance of their song NU ABO on Inkigayo. It looks like the song isn't standing out as much amongst the comebacks but it's still remaining strong among fans. NU ABO gets catchier every time I hear it and I'm completely in love with Sulli's part. One thing I don't like about their NU ABO performances is that Krystal lifts up her shirt way too high when she dances. http://www.youtube.com/watch?v=aqSFhEBPYzY
