A space-war novel disguised as a supermarket story, currently being revised
[Dream transmigration + interstellar setting + women are scarce + multiple male leads]
The main plot is about personal growth, not simply running a supermarket. Later, she will enlist.
In the future, the technology of the Universal Alliance reaches every corner of the cosmos. Every living being gets exactly one chance to enter a lottery and win a variety of prizes. But the odds are far below one in a hundred million. In other words, even among a hundred million people, there might not be a single winner.
