I have a colleague who comes to me and tries to grab my attention. He acts like romantically. I know that my manager told him to follow me and to keep an eye on me and to report her. Before that when he came to the workplace no one knew him because he was new. Shortly after he started working I found one day he stared at me and looked at me directly. After that he used to come and stared at me or sometimes in my private areas. One of my colleague found him doing that and she told him something then he used to approach to me and intended to introduce himself or wanted to communicate when he used to see me. After that my manager grabbed him and advised something so that he follows me and walk in front of me. So that he can report what I do. I don't know their exact motive. I know that he was previously interested about me so want to know now what he is doing is real or fake or cheating?
