Looking through the raws I can honestly say that its does get A LOT better. It just had a WAY to intense start, but it does get better and karma does its thing.
Also Aryas boss is by far the best character in this series and pretty much becomes Aryas real father figure and helps him out the most through this fucked up situation.
So you hate it now, I know I do, but give it like 3 more chapters and it'll get better. And fuck Aryas parents. I didnt go to deep into the raws but the amount I did read they haven't gotten any better.
