Two-dimensional culture was a sub-cultural group that originated from Japan, including anime, manga, games, light novels, and other related content. One of the characteristics of the 2D culture was that it emphasized the difference between virtual and reality. Many 2D enthusiasts would spend a lot of time in the virtual world and give themselves a special name or title. However, in recent years, as the influence of the 2D culture gradually expanded, more and more people began to realize the uniqueness and limitations of this subculture. They were no longer limited to the virtual world but began to pursue other hobbies in real life. At the same time, some 2D cultural works were gradually moving towards reality and connecting with the real world, which made some 2D enthusiasts feel confused and dissatisfied. Therefore, many 2D enthusiasts no longer called themselves 2D people but chose to express their interests and preferences more objectively. They might call themselves anime lovers, game lovers, or other similar groups instead of just emphasizing that they belonged to the two-dimensional culture. This change also reflected the fact that the 2D culture was gradually moving from virtual to reality and gradually intersecting with other cultures.
