Typical streamer friendships, they are all best friends until one of them fucks up too hard to defend, so they drop it. Natsumii got dropped because Abe is too important to the group, tech savy, sets up events etc. Easier to drop her than him.
Leslie is laying low for it to die down, but her stuff is mild, I'dnt even call her a homewrecker, seems like that marriage was already fucked up considering dude was openly talking about divorce lol But yeah she should have been smarter to not tangle with the dude until he's single.
But dont worry once she's back to streaming, I bet you won't see many of them interact with her openly, and then you will see them partying and shit on some vlogs/ig rolls xD
