첫 사랑니(Rum Pum Pum Pum) MV

It's here... F(x)'s comeback song.
It's a...hmmm...typical f(x) kind of song yet different.
After listening to it, it's so so, both music and lyrics. But I think I will grow to like it, I hope so, if I listen more to it.

As for the mv, kinda boring!? The dance and concept looks like something we have seen before. Where's the surprise!?!?!
Also I do not like Krystal's, Amber's or Sulli's hairstyles. But Luna and Victoria looks good ^^
