I can't confirm the specific name of the novel you mentioned. However, most novels had five main characters and included keywords such as " Little Butterfly,"" Elephant,"" Knife," and " Old Wolf." These were group novels, which presented a grand story line through the interactions between different protagonists and characters. This type of novel was more popular and easier to shine. If you find this novel, you can share it with me. I can try to help you review the plot.
