A fifty-yuan fine brought together two lives. The first encounter in the municipal library led to Xiao Qing, a gentle college student, and Wei Xin, a stubborn and tolerant senior high school girl like "Gu Biao". A heavy rain and a tilted umbrella become the glimmer of salvation in each other's dark moments. Family oppression and secular prejudice stand in front of them, and the class gap is like an invisible wall. However, they hold on to the agreement of "pay back the money and return the umbrella" and run in both directions. They break through the haze with gentleness and tenacity, and stand side by side in the rumors. Let Gu Biao encounter the glimmer of light and finally become the warm sunshine that illuminates the rest of his life.
