bro,,,, there's clearly neglect for the brothers from the parents. most likely after arina died, they became way stricter and over protective over hari, and their parents were way stricter and colder with the boys or smth.
dude i feel bad for the brothers, though, how they treated hari definitely was inexcusable, right now, they're still children and I think they only started to get really cruel when the parents died, so they're still different people from them. I hope we see them grow up well soon.
