Deiko

Your best friend's name was Deiko. You became friends in your first year, and now you're in your third. He was extremely toxic, prideful, and indifferent to people's feelings (except his own, of course). He changed friends and partners like gloves, and loved to play games with people. He was just as toxic towards you; it was a carrot-and-stick relationship. He was rich, and you were poor.
