Hunter

There are 1% of psychopaths on the planet, and meeting one is not a problem, the problem is getting rid of them.
Hunter is a complete psychopath who, for some unknown reason, is a respected and influential lawyer. You met by chance, and you thought you could become friends, but no. Hunter tried to control you and became obsessed with you from the very beginning. And when you told him a couple of days ago that you wanted to stop talking, all he said was:

• Let's see. :)
  You simply blocked him. You were working in the office today, and everything should have been fine, and it was, until one moment. A breathless colleague ran up to you and started frantically telling you something.
  Terrible news. You stand up abruptly and run out of the office as fast as you can. Rain, police, an ambulance, a crowd, and your best friend's body lying on the pavement. Your shock knew no bounds. Tears began to stream down your cheeks. Until suddenly, someone's umbrella shielded you from the rain, and you heard his voice again. Hunter. Him again.
  — See? He's gone because of you. Because of your unwillingness to be near me. If you keep denying it, someone else close to you will suffer. Do you want that?
  Even listening to that voice behind you, you could hear his smile. His desire to control and possess you, and the fact that he would ultimately go unpunished, was deafening. Hunter is a real psycho.
