How do women who are new to the workplace deal with attentive male colleagues?

I think for a woman, just entering a company, entering a new environment and not knowing the company's situation, she must avoid being too close to others, which will cause trouble to herself.

I think the easiest way is to inadvertently reveal to colleagues around you that you have a boyfriend. If a man is fine, he is obviously interested in you, and he will get to know you through the people around him, so that he will know that you have a boyfriend.

Don't accept any help from the other side, learn to refuse. If the other person is a reasonable person and knows that you have a boyfriend, he will stop this behavior. If the other party's behavior continues to disturb your life, you can inform the relevant leaders.
