Extremely Cold Apocalypse: Daily Survival with a Beautiful Neighbor

Okay, is it a pure natural disaster? Don't write about super-powerful monsters later. You won't be able to write about such topics for a long time. Extreme cold, extreme heat, extreme nights, acid rain, earthquakes, heavy rains, sandstorms, and tsunamis. Since it's a survival genre, don't limit it to extreme cold and one natural disaster. The inventory content is not detailed enough, and this is just an extreme cold natural disaster. There should be an official base, right? Will you go to the official base later?

Go out and suffer for a woman, [Thinking]

It's no worse than other similar novels, but I don't know why it's not rated?
