The plot of the 'Everything is Fine' novel could potentially revolve around a utopian or dystopian world where people are made to believe that everything is fine through some form of control or manipulation. Or perhaps it's about an individual's journey of self - discovery where they initially think everything is fine in their life until they start to uncover deeper issues like family secrets, unfulfilled dreams, or relationship problems. It could also be a story about a community that tries to maintain an appearance of 'everything is fine' to the outside world while internally there are power struggles, social inequalities, or other forms of unrest.
I'm not sure specifically as I haven't read it in detail. But generally, graphic novels often tell stories through a combination of illustrations and text. It might be about characters facing various challenges and still believing that everything is fine, perhaps in a somewhat ironic or thought - provoking way.
I don't have information about the main characters in this graphic novel. It could be a group of friends, or a family perhaps. Without reading it, it's difficult to tell.
There were a total of 13 volumes in the Qingyunian edition, but no specific volume names were provided. Therefore, I don't know the name of the 13th volume of the revised edition of the New Year's Celebration.
