The word "jiba" in the novel does not refer to something concrete, but is intended to express some strong emotion. It is only used to describe dreams and can be translated as "F*cking Dream". The author's mom said that I have Tourette Syndrome, and I think she is right.
This novel is adapted from the author's personal experience. It writes about the boring high school life and the dream from which I cannot wake up.
There are many intertwinings of reality and imagination. The author's limited ability may cause some ambiguities, but if you are willing to read carefully, you will be able to distinguish them clearly. It doesn't matter if you can't tell the difference. Reality and imagination are inherently absurd.
Intention: A gentleman is magnanimous, while a villain is always concerned.
