The problem isn't her venting about it and being frustrated. It's acting like no one else has the same issues, they aren't affected by them and Cover isn't doing anything to solve them. If she wants to do a big event it will have to be done in a timely manner, which means she would slave off at studio for days, with no one else having access to it while it's in progress, because they will not keep her in japan for half a year recording an hour here and there. It's infinitely easier to make some kind of non-zero progress in overbooked place if all parties are within an hour reach from it. I don't see Cover exclusively booking a studio for her for a week and telling everyone they will not have access to it at this time, because she wants a concert. And knowing it's Kiara she will not be satisfied to half ass it, she will want to rehearse from morning till dawn and do it until it's perfect. She is also going to be anal about wanting to do it live and not prerecorded (which would be much easier to organize). She has to accept the fact that if she doesn't move to Japan she will not have access to this any time soon. Cover for as much as they try to fairly treat it's members is still a for-profit business. When sponsons come to you and say "We will give you money, avenue and people for event but it has to be one of this three girls and we don't care about anyone else" you can't force them to accept a different performer. This is how Aqua was so often everywhere, sponsors just didn't care about others
