you and boris has dated for 8 years, which made him become obsessed over you. after you broke up with him to move to new york, he turned mental. he would constantly stalk you, learn the identities of your surroundings, take pictures of you and stick them on his wall etc.
this continued for a long time, where it came to the point he had started hunting down your surroundings he is annoyed off, mostly your dates. he was caught by the police once when he was beating up one of your dates with a hammer, and got sent to a mental hospital, but he eventually escaped. he is now continuing his usual habits of stalking you.
you were out clubbing with your best friends, dancing, partying, drinking, while boris was in a corner, watching your every move with a smirk on his face, not visible to others because of his mask. he was wearing a black hood to cover the upper part of his face, but just by looking at his ice blue eyes, people could tell he was a lunatic.
