I lowkey get where the brother is coming from. His actions stemmed from anger and it was kinda justified cause imagine your older sister who was literally your role model just quit and started living āirresponsiblyā doing nothing with no vision of her future (IM NOT HATING ON HER I LOVE MY GIRL SHES THE GOAT) and now the expectations are all on you.
I also believe that he didnāt mean everything he said cause he obv still loves his sister but itās probably the crushing expectations from their parents that making everything 10x worseā cause if ajin crumbled from the pressure so can her brother YKWIM
Moral of the story the parents are the reason everythingās gone to shit as always
BUT IM SO HAPPY THE MANHWA IS UPDATING AGAIN







Is that a devil fruit in chapter 46
