Well if she did, she must have a good reasons. I trust her sense. I suspect because she thought it would be the best opportunity for her group to advance further in the west with hybes new found connections after BTS success.
But so far she didn’t calculate the human element in the whole story. For whatever reasons (jalousy? pride? fear? who knows...) Hybe/Bang more specifically is not putting in the connections or even any pertinent effort for NJ's advancement in the west and are actually becoming more of a threat to the project. And a threat to the realisation of her vision and ambitions for kpop.
The last straw was probably the deleyed full album comback in february and what i personally suspect the robery of njs coachella invitation. And probably other things happening we don't know about.
Thing is bang got really arrogant after bts sucess and very greedy, maybe he thinks he can do what he wants with her. But she ain't as defensless as he thinks of her. She too as connections in the industry and a lot of experience, and if all this story is true, i personally think she is waging a war for her survival and for the survival of her vision and projects (including nj).
As i said, she is very ambitious. She wont accepts just crumbs. She aims for the top. And she probably prefers to risk it all and lose than stay in this state of mediocrity at the total control of a jealous, greedy, shady ceo. At last LSM supported her.
And for the second point, she founded Ador from a to z and owns 20% of it (which is big man). Why would she leave everything behind this easily? Lol. It makes all the sense that she tries to get more hold of her own project. It's not like she was going to take control of hybe or big hit. What's wrong with that?
(Of course as long as nothing illegal has been done. But i don’t think her stupid enough to do so.)
All this current drama looks more like Bang trying to redirect hybes shareholders wrath on the 'traitor' mhj after the coachella fiasco. And getting ride of a potential rival. Maybe his own position is threatened or being questioned in Hybe??
And if she ever gets out of Hybe, obviously she will (or at last try) take her whole project with her. From the members, to the producers, to the shareholders basically the whole Ador bone structure. And Ador will just stay in hybe in name only. Like a ghost or something. What's the point? MHJ is ador ador is mhj.
