Thirty-five-year-old architectural designer Shen Guanxue resigned from his high-paying job in the provincial capital due to a construction site accident. He returned to his hometown of Qingxi Town and took over the used bookstore "Guanxue Zhai" left by his father.
His father is deceased, his mother is far away, and the old letters in the attic hide unspoken secrets. In this small town that was about to be forgotten, he met Lin Ji, a female doctor who was also trapped in the past, and Mr. Zhou, an old man who had been silent all his life.
The seasons rotate. Snow falls, snow melts, rain falls, frost falls.
He discovers that there is another hidden secret behind his father's death. His mother's departure is not a betrayal, and he must make his own choice between "knowing the truth" and "remaining silent."
