My Sister Insists on Taking Out a Loan in the Extremely Cold Apocalypse

The temperature suddenly dropped to zero in summer. My sister thought that the end of the extreme cold had arrived, and she had to take out loans to stock up on supplies. As a socialist successor with strong roots, I advised her to calm down: The power of the country is far stronger than we imagine. What's more, the government agencies haven't collapsed yet, and borrowing loan sharks now may push your future self to a dead end. My sister listened to me and didn't take out a loan. The ex-boyfriend who betrayed her took out a five million loan to build an extremely cold safe house, and turned on the heating to eat barbecue while we were shivering. Due to the huge gap, my sister hated me for ruining her chance to enjoy the last days of happiness, so she tied me up in the snow and froze to death. When I opened my eyes again, I went back to the day when the extreme cold came.
