This is Ke Jiaji's fifth year in this city. He is 26 years old this year. The future, for him, is like an abyss with no end in sight. One night, Ke Jiaji had a long dream. He seemed to be back in the winter of his high school year. It snowed heavily that day. Ke Jiaji stood on the snow, blowing his nose and grabbing the snow with his red hands to build a snowman. Then he looked at the girl next to him and said, "I will build a snowman for you every winter when it snows."
Concept: The entire book is mostly narrated through memories and time travel. The male protagonist has distinctive character traits and is unwilling to be mediocre. After he discovered that he had the ability to travel through time, he thought he had the ability to change his life. He wanted to keep his love and his future, but in the end it was just a big dream. The idea is that the male protagonist has gone from being full of expectations for the future to now accepting the reality and becoming a common human being.
