Generally, Leaders get the worst deal of the group. While they are "in charge" of the group and its figurehead, entertainment companies tend to focus on the other members "cuteness", "agility", "genius" etc to the point where the Leader gets less focus and no chance to show off their individuality to the public (except to fans who look out for them).
As the situation develops it seems that not only Gyuri but none of the girls themselves knew what was going on!! >_< All we can do at this point is sit back and hope it all sorts itself out and KARA doesn't split up or finish... ;_;
