I'm a rather complacent, plain man. I teach science at a local high school for the disabled, and I've never performed a misdeed in my life. Hell, I've lived in wilful ignorance of the negative aspects of the world. I've tried to live the virtuous life of a family man, paying no heed to the unsavoury.
 
You can imagine my surprise when my doctor informed me that I have incurable cancer. It couldn't be karmic retribution, as I have committed no sins. Anyway, the cause doesn't matter. I have cancer, and I have a family to think of when I'm gone. We have a meagre life insurance policy which is sure to be drained in no time. Bills need to be paid, groceries need to be bought, and my son needs an education.
 
There is no easy way to make money quickly. Perhaps I should rephrase that. There is no legal way to make money quickly. It just so happens that I have a certain set of skills that will allow me to reap riches in short order. All I need is an assistant.
 
That is why I've called my most promising student into the hall today for a private proposal.
 
“Hisao, do you want to cook crystal meth?”
