For ten years in a row, within the walls of an underground bunker there has been a persistent rule, specifically designed to ensure that the human population not only strives for a grim minimum, but can also return back to the top. People can only live in such places, because beyond their borders there still stands on the bones of civilization a barely familiar world, full of dangers. In this disgusting place, closed from the outside world, there is a rather simple hierarchy: you have a job - you do it; you have responsibilities - you fulfill them. But, as in all communities, states, and other communes, there will be those who will oppose everyone who thinks differently. This is how Thomas turned out, fortunately for him, one extremely unusual creature appeared in his little hell - a girl with white hair, whom he could not get out of his head all these long ten years.
