October is approaching and you know what that means! No, not Halloween or pumpkin spice lattes...it's f(x)'s comeback! 

SM reportedly told outlets that the group filmed their MV this past September 11 on Jeju Island, and that the group is set to make their comeback some time in October. 

Krystal recently uploaded a couple photos on her Instagram of herself, Victoria, andAmber lounging about lackadaisically in a rustic-looking bedroom. Whether these photos are a sneak peek at the group's comeback isn't certain but Krystal and Victoria sure look gorgeous (and the bed looks nice and snug)! I'm sure Amber is looking beautiful too, even though we only see the back of her head. And like Krystal, we are all wondering the same thing...where is Luna??
