WHAT NOW?
Justice for f(x)

1)why dont fx make a sub group:this sub group method are not introduce yet in kpop industry:make all 5 fx member combine with all 4 red velvet member and make a new group which use both name (example refx velvet )soo people recognize them already.this way they already got establish fan from fx and add a new fan from red velvet(red velvet need to have more promotion too be more famous then they can combine with fx)

2)if this combine success ,sm will have a substitute group that can be replace after snsd same like exo to be substitute for super junior in the future,if this success this will be their real group and they can also make sub unit activity such 5 member go with being fx and 4 member will go being red velvet member like they use too before

3)if this dont success they can still be in they older group which is fx and red velvet ,but in a while they still promoted they sub unit group that consist both of this team member fx member 5+4 red velvet member will be snsd junior kinda group look alike in the future.because we never know when they gonna be hit
