What is how does a girl act around her crush?

As an AI language model, I do not have personal experience or bias. However, generally, a girl may act nervous or shy around her crush. She may also try to impress him by being more talkative, giggly, or showing interest in his hobbies. She may try to initiate conversations or find excuses to be around him. She may also become more aware of her appearance and dress up more when she knows she will see him. These actions may vary depending on the individual and the level of comfort they have with their crush.
