I've been looking forward to this ever since I heard it would have a drama adaptation cause the novel is one of my favourite. I almost had a heart attack when I heard it was released ( for one hour). The drama did justice to the arcs and characters; the actors were perfectly cast and had great chemistry. However, they changed some things ( added some characters / removed some) and removed my favourite line, which made me a little upset. One thing I didn’t like was the change in the plot for the last doors. I was looking forward to seeing the plot twist from the novel, but because of censorship, they changed the concept to gaming, which also altered the plot twist. Nonetheless, the actors, actresses, and crew all did an excellent job. The songs were also great, and the script was very well done. I'm glad I lived long enough to watch this
