Bruh, how - what !? I only mentioned their relationship and even just talking about the characters from just this manhwa no one else. I'm not even FULLY blaming her just partially since obviously people's choices (MC's or the ML's) is to blame too but of course a child does reflect on their parents behavior and the people around them so she PARTIALLY contributed to it.
I believe it's partly mother's fault. Her son hated the lil bro cause mother is too focused on making a good face for the lil bro and focused on lil bro forgetting she has her own son.
Uke hating his lil bro ain't good yeah but lil bro is also not sane.
Like bruh if he liked uke in simply "I just want brother's attention" he won't rape him
