i remember way too many small details about people so i have to act dumb sometimes so i don’t freak them out

f(x) fans who dislike this new comeback because it’s “different” from their past concepts, are a little irrating.

f(x) is called f(x) because as the mathematical problems goes, the x changes into any different number. Meaning f(x) are meant to be a group that can change concepts and fit the style but still be f(x).

The members even explain this from the beginning of the debut. They are function girls. They can be anything.
