Is there something in her contract that she can nullified it if something bad happens that could damage her career or reputation? Or is it just a straight forward contract she must follow from start to finish? Just asking.
Do you really think anybody here can answer those questions? Only herself, any legal representive who she might have hired, and the company know the details of the contract, perhaps the Japanese agency she is signed might also know.
I don't think the situation is badenough that she needs to think of doing that unless they insist on keeping Garamno matter what. They can still salvage it after kicking Garam or replacing her.
If I were Sakura, I wouldn't trust Hybe after this.
And I wouldn't blame her. It's just this is still a good opportunity that would be wasted due to HYBE's foolishness. But then again she has made a lot of money by now anyway, so who knows.
