Mental disorders are an important and dear topic to me as a bipolar patient, so I will always gladly explain and educate others about mental health. + mental disorders arent limited to depression or anxiety, they are a disorder for a reason. It’s a disability, they quite literally alter people’s perceptions and thinking, as well as personalities. It can make someone act like an asshole at times, or senstive, etc. in extreme cases, hurt someone. It’s a disability and disorder for a reason, it doesn’t make a person function properly.

To anyone saying that shinwoo should’ve just done something else other than burn the house or that he actually killed his family, or just flat out blamed him for anything (that revolves in his childhood), YOU ARE ILLITERATE. He was clearly a child and he was hungry. He can’t wake the parents up or else he’d be beaten up, all he could do was try and make something with what he had and with what jinwoo taught him.
And to the people saying that his actions don’t justify bla bla bla, HE HAS A MENTAL DISORDER! He has a split personality disorder/DID. The shinwoo that we saw when Jihun went inside his room was the real him, whereas the “fake smiles” shinwoo is the alter trying to “protect” himself. DID is a complex mental illness where you’re not in complete control of your body. It’s stated that he has missing memories, and that’s because of his other personality (wicked shinwoo). And right now, it seems like wicked shinwoo is in control of Shinwoo’s body. It quite literally means that there are two separate “people” controlling one body. And in some cases, one “personality” suppresses the other personality to have control over the body. Think of two people fighting over one entity to have control of it, before the other one gets shoved in a corner and only comes out when the other person rests. That’s what’s happening to Shinwoo, based on what’s happening so far.
It’s clear that most people won’t bother looking up or searching about a topic before commenting about it. Please, if you can’t even read a psychological or complex manhwa, don’t read it.
