This is the second work in the "Border" series. The content is relatively relaxed, contains a little suspense, and has not many chapters. I think it is quite sophisticated! This work does not seem to have much overlap with "Night City", but it is an important part of the development of the story; the time takes place when the protagonist is about to graduate from college, and the transition from school to society also means that life is completely different; the two main characters, whether in mind or body, live in different worlds, but each world is superimposed; Duan is confused about his dreams and future, and he switches between the fantasy world and the real world, feeling unprecedented experiences; Zhiyu is deeply involved in the rekindling of his old love for his ex-girlfriend, and his simple life has become complicated, because the sins caused by "deep love" also follow; bad can turn into good, love can turn into hate, just like white paper and black paper can be converted into each other...
Concept: People who read books don't know that they are also in other people's books.
