Single protagonist, no romance, spatial storage, survival, not a bleeding heart, tough as nails
The apocalypse revealed itself in 2037. Disasters struck without end, nine out of ten homes stood empty, and order collapsed, was rebuilt, then collapsed again. Humanity's evil came to the fore as people struggled to eke out a living. After enduring 14 years, the protagonist unexpectedly acquired a pocket dimension, but couldn't hold on because of dwindling supplies and died in a disaster in 17 years, an earthquake. After being reborn, the protagonist carefully planned supplies for the disaster years and fought to survive.
