I have read the novel version entitled "kaleidoscope of death" and I am also a fan of this novel. This drama was adapted from the novel and I was surprised because the storyline and depiction of each character was exactly the same as what was written in the novel. What's different is that in the novel, this door always appears when someone is about to die. and in the drama, this door is a game world that must be completed. Apart from that, the story is very similar to the novel and I wasn't disappointed, I was very satisfied with the drama! The depiction of Ruan Nanzhu and Lin Qiushi (in the drama Ruan Lanzhu and Lin Jiushi) is also very accurate. the actors played them so great. I like it very much
