Yeah i don’t know why some people here are acting like f(x) never had any mainstream hits?? I feel like with more effort on SM’s part they could’ve been more successful but at the same time if they were bigger i don’t know if SM would let Amber recover properly from her leg injury. Also it seems like Sulli didn’t like the innocent cutesy image that SM was pushing on her, so she wanted to leave plus Vic’s success in China. Exo can handle A lot of members leaving(3 in the beginning yikes) because there are so many members but with fx its more noticeable
