I like how they completely erased the twin from the story like he never existed

I'm actually wondering abt what happened to Jiwook tho. I mean, I do agree that he did really awful things. Maybe I just wanted him to know that the actual twin really did die and that he will realize that he is responsible for that. Maybe I just wanted to see him properly repenting for his wrongdoings, show some guilt. To end his part of the story like that was just too weak for me I guess. And what's Johoon going to do to him?? I'm kinda confused at that part hahaha

I feel like it wasn't dissatisfying. He knows he did wrong, that he has been played, that he will pay for everything and that nobody pities him. I think he also knows that the twin died.
