I really wonder how does that work, they clearly had to sign an exclusive contract with Starship to be able to promote with Izone. And since 7 is maximum it means they are already halfway through the contract, right?
Sakura and Chaewon had to sign a new contract, since they changed their aency but Wonyoung and Yujin didn't have to resign unless they wanted to, so I am really curious how it was or is going to be handled.
Edit: it is not even half as I said previously, Izone debuted in October of 2018, so technically their original contract is supposed to expire in less than 2 years.
