After being divided into liberal arts classes in the second year of high school, Lin Wan, a "sunshine girl" who lived on scholarships, became roommates with Shen Zhou, a "cold-faced student" who had transferred from a big city. A chance encounter after returning from a part-time job on a rainy night allowed Shen Zhou to glimpse Lin Wan's exhaustion beneath her bright smile. Two lonely souls quietly approached each other among the desks filled with test papers, but due to a carefully designed misunderstanding, they were completely separated on the eve of the college entrance examination. Six years later, Shen Zhou, who had become a well-known architectural designer, reunited under the sycamore tree at the centennial anniversary of his alma mater, the figure he had been looking for for many years - only this time, she was holding a little girl with similar eyebrows to him.
