The beginning of a novel was very important. It could attract the attention of the readers and make them want to continue reading. If you want to write a novel about an otaku traveling through the 2D world, here are some writing suggestions: 1. Description of the background of the otaku so that readers know what he likes and likes. The introduction of the concept of time travel lets the reader know that the story has changed. 3. The description of the environment makes the reader feel that they have transmigrated into a two-dimensional world. 4. Introduce the protagonist to let the readers know who the protagonist is and what his purpose is. 5. Set a suspense so that the reader wants to continue reading and learn more about the story. For example, you could write: It was an ordinary afternoon. Xiao Li, the otaku, was watching a movie at home. Suddenly, he felt uncomfortable and woke up to find that he had traveled to another world. He didn't know what had happened, but he knew that this world was different from the world he was in. He began to explore this world and found that he could control some two-dimensional things such as anime characters and game characters. He began to try to control them, but soon he found that this world was completely different from the real world. He needed to learn more skills to survive.
