I found myself very compelled by Kang Moo and Kirin. I am actually shocked we got such a sweet ending then it could have been, sure that last panel was the bittersweet part of it that Kang Moo is losing himself to his desire to kill but it's beautifully written that he sticks by Kirin for his own choice. He can easily just leave but the fact he leaves the door open for Kirin to go instead shows he's not trying to be the one to part from him. There's a twisted part of him that enjoys having Kirin around even if for a fleeting moment. And for Kirin to stay instead of just washing away this man that will slowly eat away at him is poetic. He reached out to this man (even if Kang Moo opened the door) and he is choosing to stay by him...just poetic
