Two people who don't expect to live long and have little sense of morality both plan to enjoy the moment and wreak havoc in the world.
After dealing with all sorts of random people, they realize that focusing on ruining each other's lives and stabbing each other in the back gives them a much stronger sense of being alive.
The only problem is that every plan to have the other one finish them off never goes as planned.
Detailed blurb to come.
