I know there are a lot of JYP stans among kpop fans, some really hardcore. But the JYP family persona is just that, a persona. I've listened to Min's podcast and heard enough from their former artists to know they weren't treated as well as they should've been. They caused Min's ED. Weighed her daily. She wasn't allowed to go out if she didn't meet her daily weight goals. Would be locked up. It's not normal to treat young people like that whatsoever.
To get back on the point, Somi was tired. Maybe she wasn't feeling the music. Maybe she wasn't feeling the company. People made up so many lies and rumors about her and called her a traitor, but she was allowed to leave. Knowing now how many idols hate their music and musical directions and images that were forced on them, is it that strange that she wanted something different for herself? She was so young when she joined and to her it probably felt like she was being put on the backburner time and time again. It just wasn't for her anymore and that should've been fine.
But no, people had to make up rumors that she was kicked out and things like that. Gossip and malicious things.
