In May in the border town of Qingxi, Su Yanqiu, a poor scholar, accidentally brought back the unconscious exiled woman Shen Qingwu from the Yamen in order to get money for copying books. A marriage certificate tied the two lonely people together. Shen Qingwu lost her memory and was speechless, but she hid the fierceness in her bones - to protect Su Yanqiu, she dared to confront the evil young man with an old knife; in order to support the family business, she braved the morning dew to open up wasteland and plant vegetables, and gradually learned to do farm work from a woman who was unable to tie a chicken.
Su Yanqiu was gentle and reserved, and focused on preparing for the child examination, but he always put down his books for Shen Qingwu: he was afraid that she would be tired, so he rushed to do heavy work; he was afraid that she would be wronged, so he defended her at every turn. Life in a poor family is poor, but there is warmth from the neighbors - Aunt Zhang sends vegetable seedlings, and Wang's wife helps farm the land. Even Mrs. Liu, who had had a quarrel with him, was finally moved by the sincerity of the two.
With the appearance of the light blue plum blossom sachet, Shen Qingwu's past gradually emerges: the sachet comes from the embroidery workshop in the capital, and involves an unknown identity and past. But the smoke and smoke of the humble house had already warmed her heart - instead of retrieving memories, what she cared more about was growing vegetables with Su Yanqiu on this border land, reading poetry and books, and turning the simple home into the safest harbor for each other.
