Tbh I'm not sure since the story is still new. There is some speculation that Guwon might be half dead or some experiment or something however we don't really know. Other people could also just be scared of him since he has a big figure and looks kind of gangster-ish even though he is nice and a bit dumb (at least so far from what the main character sees)
It depends what route the author goes towards. I'm so excited for this story in particular

If it is the gangster route and he's not actually half dead or anything, than it could also just be that he never really had an education and lived poorly. That could also make sense since in the beginning of chapter 1 we see him barge into a random luxurious vacant home saying he's always wanted to live in a house like that (probably meaning he didn't live very well before this)
Can I ask something what's that black thing all over guwon's body and his neck. Cause my guts tell me he came back from the dead is that the reason though? Or before he was dead he has that thing na????
Or is it too early to say this all? It's bothering me kasi eh that black thing
