In the century-old alley of "Qinglan Town", Lin Wan guards the "Light Picking and Restoration Shop" passed down from her ancestors. She has a special ability - when she touches old objects, she can sense the past memories behind them. One day, architect Shen Yanzhi brought a damaged rosewood box to a repair shop, hoping to repair the wooden box and find out its origin. This wooden box actually allowed Lin Wan to see fragments of the past between Shen Yan's grandfather and his grandmother: the two had collaborated in the old alley, using traditional craftsmanship to restore old buildings, but they parted ways due to a misunderstanding. The rosewood box was a token of their cooperation. As they repaired the wooden box, Lin Wan and Shen Yanzhi discovered that their families not only had a deep connection, but were also closely related to the storm of "style protection and commercial renovation" that the old alley was about to face. While they unearthed family secrets and historical stories of the old alley through old objects, they united with the residents of the old alley and time-honored merchants to fight against developers who wanted to destroy the style of the old alley and replace traditional craftsmanship with commercialization in the name of renovation. In the process, the two went from strangers to familiarity, from fighting side by side to falling in love with each other. In the end, they not only protected the traditional features of the "Shiguang Restoration Shop" and the old alley, but also solved family misunderstandings and allowed the traditional restoration craftsmanship to be passed on.
