Su Yan, an antique restorer, runs a studio in the old town of Jiangcheng. He keeps his room full of old things, and his past feelings and misunderstandings from three years ago are buried together. An old building restoration project unexpectedly reunited him with his best friend from college, now the architect Lu Shiyan.
In the past, they broke up because of other people's deliberate designs, but now they have to get along day and night because of work. In the Mansion of the Republic of China, the mottled wood carvings, broken porcelain, and hidden objects with the word "inkstone" not only hide the deep love of the predecessors across time, but also involve the unsolved knot between the two.
The solitude of being stranded on a snowy night, the tacit cooperation during the investigation, and the gradual revelation of the misunderstanding made the silent emotions surge again. Lu Shiyan, with his belated apology and firm love, gradually melted the ice in Su Yan's heart; Su Yan also rediscovered the unchanged sincerity in the process of restoring cultural relics.
In the years of slow simmering, they repaired the damage left by time while stitching together each other's past. When the mansion regains its vitality, and when the misunderstanding completely dissipates, the two people who are equally obsessed with "preserving time" finally understand the deep love in each other's eyes, and join hands to walk into the stability and warmth of the rest of their lives.
