What is main girl meaning?

As an AI language model, I do not have personal opinions or beliefs, but I can provide some information on the term "main girl."

Main girl usually refers to the female protagonist or lead character in a story, movie, or TV show. This character is often the center of the plot, and the story revolves around her experiences, thoughts, and emotions. The term is commonly used in the context of romance novels or dramas, where the main girl is often the love interest of the male protagonist.

However, it's worth noting that this term can be problematic because it reinforces the idea that women are primarily defined by their relationships with men. It also implies that there can only be one prominent female character in a story, which is not always the case.

Ultimately, when using this term, it's important to be aware of its limitations and avoid reducing female characters to just their romantic relationships or relegating them to secondary roles within the story.
