you actually cannot be serious? that is a bit of an insane thing to say
Wdym? I believe the backstory perfectly explains his actions in the present. Not justifies because dude was a total piece of shit but explains why he does what he does. Simply, trauma manifests in many ways that affect our behaviors and actions. Unfortunately for ML, that trauma still tightly grips at his throat but it seems like now after backstory we'll see some sort of development, hopefully.
Being adopted into a family who sees you as less than human with an adoptive brother who makes it his personal life mission to ruin your life is "not that bad"??? Being isolated from your entire life and forced to engage in self destructive behaviour, only to then be basically cast aside as soon as you stand up for yourself after your supervillain step brother exposes your sexuality to your conservative politican parents? And your adoptive father then beats the shit out of you? You get sexually harassed by your adoptive brother on top of that too and then the only person you've ever loved abandons you????? On top of that, being an outcast your entire life for being an orphan? Did you even read the manhwa.
it means his life sucks so why should he be nice to everyone :)) Plus yeongwoon did leave him out of nowhere without explaining so he was extra salty about it.
i mean the backstory is not that bad????? so why is the ml like this..
