There's a big difference between an attitude scandal and someone exposing you for being an abusive partner.
Oh, really now? Gapjil (갑질) is a big issue in Korean society as far as I knew. The general perception of hierarchical bullying is profoundly negative due to the various cases of power abuse and classism in Korea surfacing ever so often. It's easy to dismiss what you don't understand. When people get angry about these things, you have to know it’s a very sensitive topic for them on a social and interpersonal level. Don’t try to butter up the severity of this issue and downplay it as just an “attitude problem”. It's a case of workplace abuse to an employee of a lower authority. This is why Irene received a lot of flack for her offensive behavior.
*for being an abusive partner
How exactly did you come to the conclusion he was an abusive partner? That is of course if the story can be believed. I’m asking because I’m genuinely curious.
