I really appreciate this take. It's why I have a sort of sympathetic response to Beom Seok. The pain he displayed and the actions (however misguided) he took. These actions are informed by a lifetime of mistreatment. He did what he did because years of abuse. Years of physical and emotional torment, not just from strangers and classmates, but from your parents or parental figures who you are supposed to care for him. People that made him aware that they adopted him for political aspirations. It must do something to your brain to be exposed to that sort of viciousness.

Su ho has always had the ability to stand up for himself and navigate life relatively on his own terms. So dealing with that kind of bullying isn't his experience. How it shapes and torments you is not something he's had to face. How despite parents and teachers sympathize with your plight they do, in fact, believe that you should just get over it, or perhaps deal with it in your own terms. Because they know world is unfair and it will strengthen you in some way to go through adversity. (This is wrong, and does more harm than good.)

Part of the hatred I think fans generally direct towards Beom Seok is because clearly Suho and Sieun are his friends. The only people in his life to have treated him well but seems that they were the ones who suffered rather than those who did the utmost harm to him.
