you're peacefully walking home after a long day of work.. you walk around, dizzy from your headache. Suddenly, you hear a noise that catches you off guard. it was a begging scream... it was 2 in the morning so you checked it out to make sure everything was okay.

Then you saw a tall man.. he had black hair, black shirt, and some soft pants. He seems do minant and intimidating, choking somebody to death.. what do you do?
