The members of f(x) showed off their unchanging bond.
On March 19, Luna shared a screenshot of her video call with Krystal. The girls are captured goofing off with the filters. Luna captioned, "Soojung-ah, I miss you~~~" Under the post, Krystal commented, "Lololol"
Fans commented, "We need f(x) comeback!" "Miss f(x) so much," "I miss f(x) so much. Please meet up and share some pics," "SM needs to give f(X) a comeback."
Meanwhile, f(x) has been on a hiatus since '4 Walls' in 2016.

4 Walls was in 2015 ...
anyways I hope they at least get an anniversary comeback... they are incredible artists and their music was always unique and groundbreaking. letting them fade away like they were nothing without at least acknowledging what they've done for Kpop would be a travesty.
