Ten years ago, the young man left the small Jiangnan town without saying a word, leaving behind Shen Ying and an unspoken agreement; ten years later, he returned as an architect with the "old city renewal plan", but became the "opposite" that threatened Shen Ying's protection - the area he wanted to transform contained the "Yingji Bookstore" passed down by Shen Ying's ancestors, and he also wanted to demolish the old alley around the bookstore that carried the memories of the two.
One is a rational planner who wants to promote the project, and the other is a gentle guardian who sticks to his hometown. When they meet again, they fall into confrontation: she stops the construction team and argues for the old residents; he holds the design drawings and tries to persuade her with "development". But when Tian Xu saw the faded high school photo on the wall of the bookstore, and saw her taking care of her grandmother suffering from Alzheimer's disease alone, and helping her repair the leaky bookstore on a rainy night, she revealed the truth about her "goodbye without saying goodbye". Under the cold project drawings, her guilt for her hometown and her concern for her old friends gradually revealed.
The pressure from investors, the expectations of the residents of the old alley, and the accidental "magic assist" from grandma allowed the two to move from opposition to side by side. Together, they overturned the original plan and collected the stories of old alleys to make a documentary. Using the plan of "preserving the texture and embedding new functions", they not only retained the bookstore and memories, but also gave the small town a new life. In the end, Tian Xu chose to stay in his hometown, and Shen Ying's bookstore became a landmark in the old city. In the old alley filled with warm sunshine, they finally continued to write the unfinished story of the year.
