Nicole posted a long tweet clarifying what she had in mind with the contracts, which is different from what went public. Basically, she wants to be a freelancer, to not belong to DSP, and yet have the gig of being a Kara member. She seems confused as to why it was made public, but I think it is a pretty clear message from DSP: It is not fucking happening, girl.
This would not only be unfair favoritism as the other members have signed a few more years of their life away to DSP, it would be setting an historic precedent in the whole industry for such a thing. No agency wants the reputation of one of their primary sources of income to be subject to the private decisions of individual members in what kind of deals they make with whoever else (the competition) or how they live their lives.
So, since Nicole seems to ultimately believe in what Nicole wants to do (not a bad thing), and wants to let Nicole have freedom yet also stay with Kara (lmao), it is pretty obvious she has fangirl-level delusion about herself, or has at very least allowed her mother to influence how she thinks about herself to such a level. If it actually works out for her, well I think that would be the biggest news in kpop for the last 10 years, but I don't think it will, and as she has already decided, she will be on her own.
Good luck becoming a star on your own, Nicole. It is a hyper-competitive market filled with the ultra-funded, ultra-talented, or ultra-pretty (by extremely narrow Korean film world tastes) and well... I love you but I think it will be hard for you. Talk to Jay Park for tips on how to get by okay.
