but she was trainee in JYP for a long time, as we know from Momo that they would hang out together while Momo was still a trainee, so that means at least 7 years? (probably more)
So even if she was in nmixx for a rather short time, she still has a long connection to the company, so I find it understandable that fans think she might return.. (I do not believe that will happen myself)
There aren’t any cases i can think of where a former group member came back after leaving. And i can list many many idols like this from ONF Laun, Ghost9’s two ex-members, winners ex-members, wjsn china line, monsta x wonho, purple kiss jieun, oneus ravn, ranias many ex members, idle soojin, dkz’s two members, tvxq ex three members, ikon bi, treasure’s two former members etc. you can make the argument for all of them that they spent a lot of time training and some have been in their groups for years, but none of them ever returned. And not all of them have huge controversy under their belts either.
honestly, I can’t make a broad blanket statement as to why this is as the situations are different for every group and member, but what i can say is that a lot of times, especially when the group is doing stably well, companies are unlikely to start up controversy and rock the boat. Again, I’m sure most would be happy with jinni’s return but with many unknown variables and how stable and well nmixx is doing, it is unrealistic for jyp to make big risky moves like that. They have a bottom line to think about.
