f(x) is a South Korean girl group. The five members of the group are Krystal, Victoria, Amber, Sulli and Luna. They first caught my attention when my cousin introduced me to their hit song Nu ABO. I love the song! I also searched for their previous released songs like La Cha Ta and Chu~. Both were pretty good. Then this year they released an album featuring hit songs like Pinocchio (Danger) and Hot Summer. Both songs are remakes of other people's songs I believe but it still doesn't change the fact that they are good songs. And they dance very well too. Kudos to them, I'm very impressed.
I believe fan of K-pop would already know them but if you're new to this genre, please search them up. You can easily find their music videos on YouTube. They are beautiful, talented and pretty cool. I still haven't found their album in my hometown but hopefully I will soon.
