The Biggest Problem of a Fangirl is seeing the group that she loves the most gets torn apart, get replaced by new members, disbands sepearately,a member leaves the group.
They debuted as one group and they will stay like that in my eyes. 
I just can't believe this. It really hurts seeing the group that you love gets torn apart.
I can only accept that they disband all together.
Isn't it all for one, one for all?
Where did that go? Why are some groups becoming like this?
