I can't believe some of y'all are comparing Jiwoon to some seriously messed up toxic characters. What he did by isolating and starting to get possessive is totally wrong and toxic, no one should defend those but he wasn't like this to begin with. He originally did those to protect him while he dealt with the red head. Yes it was still wrong of him to not mention that to Suha but even then we have to think of the fact that this man has seen the man he loves be abused many times in the hands of that man so I'm sorry but I can see why he didn't tell Suha. I'm not saying I support it or he was right but I can see where he is coming from. He never did those to idk abuse Suha. He had Suha's best interest at heart at first. However, he is a damanged character that does need therapy because his biggest and worst nightmare being abandoned by someone he loves again is constantly being triggered by the shi*** people he calls family. Like all he sees are people telling how unlovable he is and how bad he is. Even the servant were talking down on him.
Like look at the way Suha's other hyung (long haired who i really like) treated him. He nicely told Jiwoon to wait until both of them calmed down and come again another day. And Jiwoon accepted that and left even if it was hurting him. And Suha told him he wants space so from what we can see in this episode, he is giving it to him.
I don't understand how some readers decided to accept Jiwoon as satan reincarnation and hate him with so much passion lol. I personally love him as a character and think he deserves some peace and happiness just like my precious Suha. I even hope they find that happiness with each other under better and healthier conditions.
