Stans spent eternity arguing whether JYP kicked Somi out, or the latter turned out to be a prodigal son, backstabbing JYP and leaving for the competitor. Whether "Yuna>>>>>>>>" or "Muh Teddy music>>>>>". But in the end, I think it is pretty clear that both Itzy and Somi would be doing better together. Somi has something Itzy lacks and Itzy has something Somi lacks in order to hit daebak.
Personally, if it was Somi's choice, I totally understand her. She's a traumatized kid, going through not just one but two survivals, and then being in a limbo for a while. Something could've broken in her. But if it was JYP's choice to not debut her with Itzy, then honestly, fuck that guy, again.
