Monsoon Blows Old Letter Paper

When Su Wan was repairing a 1947 clock, she found half a piece of letterhead sandwiched between the gears. The handwriting was blurred by the rain, leaving only "... When the monsoon blows over Qiantang again, I will marry you." That night, Lu Zhiheng, the curator of the ancient books library across the street, came to visit unexpectedly, holding the other half of the letter in his hand - he found it when sorting out the archives of the Republic of China. It was signed "Shen Zhiyi" and the recipient was "Su Nianqing". The two launched an investigation to piece together a complete love letter, but in the process they got involved in each other's past: Su Wan's mother, suffering from Alzheimer's disease, always muttered "Zhiheng will come back" to an old pen; Lu Zhiheng's grandfather Shen Jitong, before his death, clutched a faded cheongsam photo and said "I'm sorry to Nian Qing". As more old objects are restored (a pen engraved with the word "Wan", a cheongsam button embroidered with the word "Zhi"), a love buried by war and misunderstanding gradually becomes clear: In 1947, Su Wan's grandmother Su Nianqing, a well-known cheongsam tailor in Hangzhou, fell in love with Shen Zhiyi, a watchmaker who had returned from studying abroad. Out of jealousy, Shen Zhiyi's brother Shen Jitong (Lu Zhiheng's grandfather) forged a telegram announcing Shen Zhiyi's death and tricked Su Nianqing into marrying someone else. When Shen Zhiyi learned the truth on the battlefield, he had become a revolutionary partner with a comrade arranged by the organization. He could only break the love letter into two halves, hide one half in the clock, and entrust someone to deliver the other half, but they were lost due to the war.
