The modern supermarket industry is heavily involved in involution, so I hit it off with the system and moved the supermarket directly to the apocalypse.
If I earn enough apocalyptic currency specified by the system, I can return to the modern world with all my wealth.
The instant noodles, hot drinks, and various medicines on the shelves are all luxuries that survivors compete for in the last days when supplies are depleted.
Among the ruins, my shop always shines with warm light. I guard this supermarket, sell goods in exchange for survival resources, and focus on making money just to go home as soon as possible.
Philosophy: It is difficult to survive in the last days. The heroine runs a supermarket and stands firm in the troubled times. She sticks to her heart and strives to find a way back to modernity and realize her self-worth.
