I also come from difficult family, drinking father, always working mother also grandma and grandpa rising me. My childhood wasnt easy but this isnt excuse for me for such behaviour. Leaving anger and other things aside, just look at the way he treated Jooin, like someone who is an irritating grabage
everyone reacts to different situations differently, im not saying that his situation justifies his behaviour, because it doesnt, ik bc my brother is very toxic manipulative and abusive even though we come from the same situation, but all im saying is that he needs therapy and should 100% never physically hurt jooin

as somone who comes from not a great parent relationship, i can confirm it changes who you are and ur perception of life. i have so many anger issues now and i can tell yawhi does too and i can tell he regrets his actions, he doesnt have any excuse for what he did, but i know that he cares deep down, but when he fixated all that anger and frustration into physical abuse thats where i draw the line. aproaching somone physically is never excuseable and i understand that hes not in a good state of mind and he has a bad past but he should jot have put his hands on jooin, hes just digging himself a deeper hole. i think that if he hadnt done that he could have had a genuine chance, and ik hes hurt, put hurting other people just because you are is never the solution :/
