This is a very anticipated comeback for f(x) so news outlets are updating us on every step of their preparations!

A representative from the music industry shared, "f(x) filmed for their new MV in utmost secrecy on Jeju Island today (September 11)."

The four members were said to have arrived at Jeju in the morning and were being careful as possible to not reveal their album concept to prying eyes.

The hype and interest for f(x)'s comeback this fall is even higher than usual, since it will be their first comeback as a four-membered group, and their last comeback was over a year ago.
