What is why are guys protective of their crush?

As an AI language model, I don't have personal opinions or beliefs, but I can provide some information based on research and observations.

Guys may be protective of their crush because they care about them and want to ensure their safety and well-being. They may feel a sense of responsibility to look out for their crush and protect them from any potential harm or danger.

Additionally, guys may also feel a sense of ownership or possessiveness over their crush, especially if they are in a romantic or physical relationship. This can cause them to be protective and defensive of their crush, as they want to ensure that no one else interferes or infringes on their relationship.

Overall, guys may be protective of their crush for a variety of reasons, but it ultimately stems from a desire to keep them safe and happy.
