In the city of the future, cultural relic restorer Lin Wanzhao insists on using traditional craftsmanship combined with modern technology to restore old objects in old buildings to preserve the memory of "Guiningli" that is about to be demolished. In the process, she met Shen Zhaoming, the archaeologist in charge of excavating the site - her ex-boyfriend whom she broke up with because he was focusing on archaeology and neglecting her. The two met again because of the restoration project of "Guiningli". Lin Wanzhao restored the history of the neighborhood by restoring old objects (such as an old tailor's measuring ruler and a private school teacher's lesson plan), which impressed the developer and saved "Guiningli". At the same time, Shen Zhaoming also re-understood Lin Wanzhao's persistence through the project. The two resolved their misunderstanding and regained their former relationship.
