In the misty rain in the south of the Yangtze River, the old alleys are long, and the rain is like a curtain lightly covering the bluestone slabs. The heroine Su Yao comes from a well-known local scholarly family. She is beautiful and charming, and her poems and songs are all perfect, just like an apricot blossom swaying in the mist and rain. Although Gu Chen, the boy next door, comes from a poor family, he is handsome and has great ambitions. He wants to gain fame, change his destiny, and give Su Yao a stable and happy life.
The two grew up together, and their love grew secretly. Gu Chen studied hard day and night, while Su Yao added fragrance to her red sleeves. But the gears of fate turned quietly, and Su Yao's family betrothed her to a noble son from a noble family in the capital for the sake of the family's glory. After Gu Chen learned the news, he was so anxious that he rushed to the examination room day and night, just to be able to keep Su Yao by his side as soon as possible.
On the day of the wedding, although Gu Chen was a high school graduate, he still failed to stop Su Yao's sedan chair. Su Yao lives a miserable life in her new husband's house, facing complicated house fights and an indifferent husband. Gu Chen struggled in the officialdom and was promoted along the way.
Many years later, on a misty and misty day, Ren Yao, Gu Chen, Ren Yao and Ren Yao, Su Yao and Ren Yao met unexpectedly in an old alley. The moment their eyes met, memories of the past came flooding back. At this time, the love in their hearts is still as hot as ever, but the shackles of the world lie between them. Can they break through the obstacles and regain the deep love buried by time?
