I doubt Cube would do that. Imagine the sisters going to Dispatch with evidence that they are being bullied by Cube. Cube would not want the anger of the GP. They would not want to go bankrupt. Putting it bluntly, why sacrifice a whole company for one idol. That strategy is just dangerous and asking for trouble.
that's on Cube's prerogative right? like i said total war...
if you want to keep Soojin...which they seem to want to do - the alternative is to get rid of SJ...
what would you have Cube do to keep SJ and not "fight"
