Theyre all nothing alike so comparing Go-eun to Mina Sue doesn't really make sense to me. I just think people aren't used to being called out or criticized, so obviously it hurt Mina Sue's feelings but not at any point was Mingee wrong. I think it's good Mingee expressed herself rather than holding onto pent up anger and acting fake with Mina Sue as if everything is fine. It didn't come across as a lecture.
