The two met for the first time on a snowy night and became connected through a copy of "Annotation of Dunhuang Posthumous Letters". Their common love for Dunhuang art made them fall in love after they reunited at the Mogao Grottoes. Shen Zhiheng gave Lin Weiyan a crescent jade pendant engraved with the word "Word" and promised to find her after handling the matter. However, this agreement was broken due to an elaborate conspiracy - Lin Weiyan received intimate photos and IOUs of Shen Zhiheng and a strange woman, mistakenly believing that he approached her to use his father's power to pay for the debt of the museum. Shen Zhiheng was framed by his uncle and found himself in an unexplainable predicament.
In the past five years, the two lost contact. Lin Weiyan became a restorer of cultural relics, while Shen Zhiheng suffered everything silently. It was not until Lin Weiyan was sorting out his father's belongings that he discovered the flaws in the anonymous emails and Shen Zhiheng's letters from that year, and learned the truth. She rushed to Dunhuang, only to learn that Shen Zhiheng had passed away from stomach cancer, leaving only another jade pendant engraved with the word "Zhi Yan" that could be combined with it, and the word "Waiting for You" hidden in the flying ribbon in the Mogao Grottoes mural.
This love was eventually shattered by time and misunderstanding, leaving only eternal longing and irreparable regrets, like broken jade, which leaves traces but is difficult to recover.
