Generally speaking, when reading apocalyptic novels, the protagonists mostly return to the countryside to survive. I wanted to write a story about how a person survives in a commercial house in his city after the apocalypse arrives.
Farming articles, trivial daily life, have golden fingers.
The protagonist is male, but it is estimated that there will be no attacks, and someone will single-handedly target him. Write whatever comes to mind, just follow the circumstances.
Purpose: Survive well in the apocalypse
