Thousands of people have thousands of first loves, each one like a blooming flower. In the torrent of time, flowers always wither, and I always feel sad about this. And I picked one up and gave an appropriate description, which is the best imprint of life and youth. The novel is based on a true story, with beautiful writing style, implicit narrative and rich meaning. It takes the first love of Song Baoqi and Wang Qianqian as the main line, recalling a dusty past.
