That doesn't give him the right to be hostile to other Betas and treat them like trash!!
Sumi is a MAJOR asshole!!!

No, actually it does. It's a certain defensive mechanism. Just like when you abuse someone, be it an animal or a human, they will either try to get away or be aggressive. It's given after what he went through. I do find him somewhat annoying as a whole but I do understand where is all the hate coming from.
Sumi is lowkey an ass but it's fine because he went through a lot. Love Utou.
