Few stories can have a good impactful ending. This is certainly one of them. From the very beginning we see what Mujin can do to keep Cho-ah for himself and how unconsciously Cho-ah doesn't want that. I knew it wouldn't have a happy ending because Mujin is fking crazy but never have I read a perfect ending such as this one. 10/10 would definitely recommend.
