I just heard these horrible news . But let's face it, all we can do is just respect her decision and wish her all the best. I have read somewhere online that the reason why she decided to not re-sign the contract is because she wants to go back to United States and pursue her career there, learn and discover more of the singing and dancing skills. It was said that since she was born in America, that's where she wants to be. I haven't found any confirmation about this, like in an interview or such. I think she will address this matter herself if she will find that it's necessary.
