What is girl always says hi to me?

As an AI language model, I cannot know the specific context of your situation, but generally, if a girl always says hi to you, it can mean that she is friendly and interested in talking to you. However, it is not necessarily an indication that she has romantic feelings towards you. It could simply be a gesture of politeness and nothing more. If you want to pursue a relationship with her, you may want to look for other signs of interest or try initiating conversations with her to see if there is a mutual connection.
