In the autumn breeze of Xicheng, Fu Huaizhu once thought that youth was the smoke of fireworks in small shops, the fragrance of pen and ink on test papers, and the tacit understanding of unexpected encounters with Zang Fanyue in games. After the college entrance examination ended, she went to the Law Department of Haicheng University, where she reunited offline with the young man who instantly came back to her in the game. She also met the gentle and protective senior Gu Jiuci and the bright and transparent school beauty Jiang Wantang. From online to offline, from campus to daily life, her love for Zang Fanyue grew through sharing, and her two-way confession shocked the entire youth. But the distance of four thousand kilometers and the different family backgrounds finally became a chasm that could not be crossed. The worries of the Fu family's parents and the collector's family prejudice crushed this pure love. Zang Fanyue was forced to accept a business marriage and made a marriage contract with Gu Mingyue; the heartbroken Fu Huaizhu married Gu Jiici, who was always by his side. In a misplaced marriage, Zang Fanyue became the tool of the family, indifferent and sinking in the shopping mall; Gu Jiuci used gentleness as a blade to melt the ice in her heart little by little. When Fu Huaizhu finally saw the deep affection of the people around him, he was sentenced to death by a rare serious illness. Before she died, she felt extremely guilty about Gu Jiu's words, but she could not completely forget Zang Fanyue. It wasn't until her death that the Jiang family revealed the truth - she was originally Jiang Huaizhu, the long-lost daughter of Jiang Zhijing, the richest man in Xicheng, and Zhao Yunshu, a medical family. Zang Fanyue went completely crazy after hearing the news of his death, and was trapped in a mental hospital for the rest of his life and died of depression. A meeting that started in autumn ended up being a regret with no return date. All living beings have achieved perfection, except for the years when she was buried, he fell into madness, and the love hidden in the autumn wind eventually became an irreparable tragedy.
