The novel reading network didn't put it on the bookshelf. Why did it show that it was put on the bookshelf?
The novel reading website was an online novel reading website. It usually automatically categorized some novels that had been uploaded to the website into a "read" bookshelf for users to view. However, some novels might not have been uploaded to the website yet, so the information about the novel would not be displayed on the bookshelf. If a user found that a novel had not been uploaded to the bookshelf when they were checking it on the novel reading website, it might be because the novel had not been approved by the website administrator or because the website was being maintained or updated, so the novel could not appear on the bookshelf. If the user wanted to check the details of the novel, they could click on the "Details" button to learn more about the novel, including whether it had been uploaded to the bookshelf, whether it had been approved, and so on.
