f(x) Luna's "I Love You" is for whom?

f(x) Luna's latest post goes with the caption saying, "I love you so much ♥". 

Is it for someone special, is she dating?  We doubt it considering f(x)'s busy promotional schedules for '4 Walls' but its not impossible, and if that's the case we wouldn't be against it either.

For now, we'll gladly take it as her sweet message to us fans~
