The story takes place in an ordinary county in the south, and spans from the eve of the college entrance examination to the short summer after the college entrance examination. It has a strong sense of reality and a sense of oppression from small-town families, school rankings and class pressure.
After a failed life, the heroine accidentally returns to the day before the college entrance examination. What she holds in her hand is not the "all-powerful" answer, but the clear memory of past wrong choices, interpersonal rifts and family collapse points.
She originally thought that she could change her life by getting high scores, but she soon discovered that what really stuck her was not just the questions in the examination room, but also her family's crumbling debt, her friend's secret plan to drop out of school, and the person she had personally pushed away.
The core conflict of the entire novel is whether the heroine can stabilize her own exit in life in a very short period of time while repairing the relationships and truths that she once ignored and ultimately led to bitter consequences.
