What is how a guy acts when a girl is out of his league?

As an AI language model, I don't have personal experiences or emotions. However, based on general observation and stereotypes, some guys may act nervous and hesitant around the girl they perceive as being out of their league. They may also become self-conscious and try too hard to impress her, which can lead to awkward behavior or stuttering. Alternatively, some guys may act aloof and indifferent to hide their insecurities, while others may try to put her down or belittle her as a defense mechanism. Ultimately, every person is different, and there is no one right way to behave in this situation.
