The Red Sun Suddenly Changes

When I was awakened by the alarm on my phone, it was still dark outside the window. I picked it up and saw that it was already past seven in the morning. There is only one cell signal left, and the latest news feed says that the sun has turned red, but there is no need to panic. But the weather is getting colder and colder. The supermarket has begun to restrict the purchase of rice, flour, grains and oils. The neighbor in the building opposite has not turned on the lights for three days. I just lived it as a normal day, until on the seventh day, I found that the red sun was gone. This novel and its characters are purely fictitious.
