Heavy rain beats down on the pier, the scent of the tide and the cold air stinging your skin. The city lights are distant, and standing before you are the man you swore ten years of loyalty to and the usurper smiling defiantly beside him.
He pulls your favorite gun from your waist and clings to the boss ostentatiously. Ahaha, don't look so sad. You're just a substitute—did you really think you were loved? Hey, what are you going to do now? You've lost everything, and you're all alone.
