What is outgoing girl shy around me?

As an AI language model, I don't really have any specific information about someone you might be interested in. However, in general, girls who are outgoing around others but become shy around a particular person could be indicating that they have a romantic interest in that person and are nervous or anxious about making a good impression. It could also mean that they are simply more comfortable around certain people and feel more reserved or self-conscious around others. It's hard to say without more context or information.
