In September, when the leaves of the sycamore trees were falling, the manuscript of Xia Zhi, a girl from the radio station, unexpectedly landed at the feet of Shen Juan, the god of science. One is a bright and transparent "little sun" who relies on part-time jobs and scholarships to support his life, and the other is a taciturn and cold "campus iceberg" who wraps up his uneasiness with his grades. The two people who have never met have their hearts shaken by the monsoon wind because of a stray cat, a book of annotated essays, and a shared umbrella on a rainy night.
From the physics laboratory to the corners of second-hand bookstores, from anonymous piano accompaniment to New Year's Eve confessions, they walked side by side in the three years of high school: there were the distance after class placement, family troubles, and the determination after the misunderstanding was resolved; they supported each other through the difficulties of competition and academics, and they also witnessed the secret love of their best friends and the decision to grow up. Finally, the college entrance examination results were released, and the admission notice from the southern city held their hands. The wind on Wutong Street was still blowing, and their story had just begun.
