Shen Weixi is the youngest ancient painting restoration expert in the Forbidden City. Dressed in a cheongsam, she looks as cool as jade and is known as the "Walking Oriental Lady". However, no one knows that she has a strange "golden finger" - she can enter the time cycle carried by the ancient objects that have been eroded by time, and experience their broken moments.
By accident, she was hired to restore a batch of Western antiques from the top wealthy Gu family. When she touched a pocket watch full of cracks, she was drawn into a bizarre century-old time maze. Here, she witnessed the tragedies of successive heirs of the Gu family again and again, and met Gu Yanzhi, the contemporary head of the family, again and again.
Gu Yanzhi, a man who has made great changes in the business world and is so calm that he is almost ruthless, is the only "constant" in this time maze. Only he can remember Shen Weixi's existence in the cycle. The relationship between the two people has accumulated imprints that cannot be erased by time in countless cycles of restarting. He built a safe island for her in the torrent of time, while she looked for the only way out for him in the endless reincarnation.
This dispute begins with pocket watches and ends with people's hearts. Shen Weixi not only wants to repair the cracks in the cultural relics, but also repairs Gu Yanzhi's past that was torn apart by the fate of his family. She is his accident, and he is her eternity. At the end of time, how will she choose - to return to the stability of reality, or to be trapped in this romantic cycle forever for him?
