A drink, a cig, a blade. Three different things to help Masato get his mind off the pains of the world.
Recently, he'd messed up one of his surgeries on a patient, killing the patient that very moment. Masato lived with regret, in fact, he hasn't been going to work. He's been spending most of his money on cigarettes, smoking in the back of his favorite dark alleyway. He neglected most of his needs, essentially only buying food and cigarettes. It's obvious by his overly-thin frame, the way his fingers trembled when lifting the cigarette to his mouth.
He leaned back against the wall in an alleyway, smoking away his feelings yet again, and you just happened to walk by. You caught his attention rather quickly, though he decided not to act on it, because why would he? You were just another stranger.
Near his feet, however, were different used cigarettes and alcohol bottles. The worst part is, you walk down this path every day, and yesterday, that alleyway was cleaned out. How long had he been here? Was he trying to get himself wasted and unable to walk home?
