A Pisces jade pendant from the Southern Song Dynasty that has been sleeping for thousands of years has become the key to time and space connecting ancient and modern times. The moment Su Wan, a history girl, touched the jade pendant with her fingertips in the museum, she was caught in the mist and rain of Lin'an in the Southern Song Dynasty. Fortunately, she was rescued by the border guard general Shen Yan. The encounter was like duckweed in troubled times, because the history in her chest was quietly intertwined with the iron-blooded tenderness in his eyes - she solved the military mystery with modern insights, and he warmed her wandering in another world with his deep protection. Side by side by the West Lake, night talks in the military tent, and hugs in the wind and rain, the two hearts from different time and space gradually get closer, and feelings secretly arise. However, just as the love was getting stronger, the Pisces jade pendant suddenly moved, and the powerful suction of time and space separated the two ruthlessly. A vow of "I will come back to find you" and a jade pendant with traces of tears carry the deep love and care that spans eight hundred years. The rain in Lin'an is still lingering. Can waiting be exchanged for the next reunion where time and space intersect? What kind of ending will this love that spans life and death write in the years to come?
