If they're starting an official deal with them now, they should have a press conference for it, especially if any of the kamikaze kids are going to be involved with it. I think I'll wait for that press conference before I fully believe everything.
I know a lot of people who work for Grammy and am close friends with a couple Grammy artists, but does that mean I know everything behind the scenes that Grammy is doing? Hahaha, I wish~ I think unless you can specifically state sources, everything is just rumors and speculation people will just take with a grain of salt. I mean, even staff can misunderstand something or the story gets warped on its way down the grapevine, so perhaps there was a misinterpretation or exaggeration or embellishment somewhere.
The thing about Waii supposedly being in 4 Minute that's so hard to believe I think is the fact that legally it doesn't make sense, if she's under contract with RS, she can't just run off to another country and sign with another company and get into a group right away with no prior training and without even being able to speak the language..
At least the original rumor seemed more feasible, since it said Waii wouldn't be renewing her contract and wanted to sign with JYP, but then you said she already
did go to Korea and sign with them, which doesn't make sense because she's still with RS, as you
then said she
was sticking under RS contract in another post right afterwards, and legally she
can't sign with JYP until her contract with RS is expired unless she wants to go through the legal process of ending it early... But then you say that she's working on a new album, so unless she wants to just throw that away, she will stay with RS. So, following all that, the solution that makes the most sense is that if JYP and RS are signing a contract so they can work together, Waii is probably in line to get a special project most likely a collaboration group with a Korean artist, and like Golf-Mike and Ice Sarunyu, if the Korean audience accepts her well and she does good, perhaps perhaps then JYP would even offer to sponsor and produce a Korean album for her.
That's the scenario that makes the most sense to me given all that has been said thus far

Perhaps she was going to do a collab with 4 Minute. Perhaps she IS going to do a collab with them, she still hasn't announced what her special project in Korea is going to be, that could very well be it. All will be revealed shortly, right? haha I'll look forward to that press conference~
