The father of our Lin siblings is a top meteorological scientist in the country, and everyone in the family is young and promising. My beautiful sister with long, straight black hair became a university professor at almost 30, while I had just graduated from university and was doing nothing. The relationship between my father and I has not been good for a long time. My sister sees it and feels pain in her heart. Until that day, my parents died in an accidental plane crash. At the same time, the ice apocalypse that swept the world broke out. I woke up half asleep in the rental house, and saw my sister standing at the door wearing a thick down jacket, saying she would take me somewhere. I asked her where she was going, and she said the safe house my father left before his death was in the suburbs. There is enough room for us to live there for more than ten years. We will have a hard time surviving here for a long time to come. It seems that we, brother and sister, will have to share the joys and sorrows together.
