When I saw a twitter account making a list on why the boot was sketchy I was over it. I was like 'please, don't do this right now, I don't want to read this'. The tweet might be written by an angry young fan on a note app with spelling mistakes that make it not look credible, but after reading discussions on Reddit pointing out the same problems, I do agree that this case seems really odd/suspicious.

From a business standpoint, it doesn't make sense to eliminate a member in the middle of a comeback preparation, wasting all of that effort, resources, and capital they've already spent. The team and SKZ members also would have to work to re-record, re-shoot, re-do their performances in a short amount of time. And especially the performance part, this doesn't only affect their upcoming album but ALL songs in their entire discography. They'd have to figure out who's going to cover Woojin's part and how they're going to re-do the coreo. Woojin's a main vocalist too, his range is quite high and I wonder who would do all of his parts.

JYP made the statement and cleared everything about Woojin from their site and upcoming SKZ album preview so fast, it does raise the suspicions that they want nothing to do with him as fast as possible to avoid further damage.

People are speculating on whether Woojin left because he wanted to, or JYP kicked him out. 'Personal circumstances' could be anything, really. It could range from serious crimes which could harm the whole company and group's image like drugs or assault, to stupid shit like violating the rookie dating ban. If it is indeed something bad, then it's clear that JYP wants to distance themselves from whatever happened as fast and as clean as possible, and everyone involved in this signed an NDA so that whatever it is won't leak out to protect the group and company.

JYP's statement is very similar in wording to the case of Day6's Junhyeok back in 2016 after his dating scandal. The difference is that, there was a scandal to relate to back then, and in Woojin's case there was nothing that indicates that he is in any kind of troubles preceding the announcement. Both termination was quick, and without a word from the terminated party. It's hard to tell at this point whether the person involved is silenced by the company or chose not to say anything.

Of course, with the ambiguity of the (translated) statement, it could mean both ways, it could mean anything.
1) Woojin left Stray Kids because of his personal reasons, there are no other options, we respect his choice. He terminated his exclusive contract. Please continue to cheer on both Woojin and Stray Kids.
In this case, personal reasons could mean illness (physical or mental), family matters, creative differences, irreparable relationship with the team due to personality differences, etc.
2) We had to let Woojin go because of his personal circumstances that we can not accept. We terminated his contract. He's on his own now, you can continue to cheer on him if you want, but please focus on Stray Kids.
In this case, circumstances around his personal life could be dating despite the dating ban for rookies, maybe he dated a fan?? Or idk, did drugs, money laundering?? Assault? Did he hit someone?? It could be anything, really.

If it's mental problems, JYPE would've facilitated Woojin to get better and give him options whether or not to participate in the next comeback or other activities like TWICE Mina.
If it's creative differences, JYPE would've stated so just like Somi when she terminated her contract.
Unless it's something really bad that resulted in immediate termination, JYPE could've put him in hiatus and then terminate his contract later like Sunmi or Jay Park.

Chan left a message on SKZ's fanship board and this too could be interpreted as anything. People said Chan not even mentioning Woojin's name as a 'red flag' but we don't know. He's trying to address STAYs because, at this point, no one is saying anything other than JYPE and the fandom is confused about what happened. I think not mentioning the name could just be part of the contract to not involve a person in any way anymore as soon as their contract is terminated. Legal reasons. Or out of respect because Woojin does not want to be involved or mentioned. It could be anything. One thing I know for sure is their bond will never be broken. They went through so much together.

People keep comparing the case with Hwall (as I did in my last post) but in Hwall's case, we're aware of his health problem from a year back. Hwall ended his activities with TBZ but did not terminate his contract with Cre.Ker. The circumstances around the two cases are too different to compare.

Honestly, the K-Pop world is full of secrets and most companies are hush-hush about whatever happened internally. Unless Woojin or an insider starts to talk, I don't think we'll ever know what happened. And I also don't know if Woojin is going to pursue celebrity life after this.
