Shen Hengyu, the legitimate daughter of the Shen family in Jiangnan, was born gentle and beautiful. She was good at playing music, chess, calligraphy and painting, and her dancing skills were even more outstanding. The world only thinks that she is a scholarly noble girl who was raised pampered, but they don't know that she was exposed to pharmacology due to her grandmother's illness in her early years, and secretly learned the art of combining fragrance and medicine, which can save and hurt people.
She and Pei Yan, the eldest son of Chengenhou Mansion, resigned from their childhood sweethearts and made an engagement since childhood. Before moving to Beijing, the young man promised that he would find a matchmaker to marry her when she comes of age. Unexpectedly, Huo Yunzhu, a noble girl in the capital, fell in love with Pei Yanci at first sight. She forced her to marry Pei Yanci at the risk of death, and forcefully intervened between the two.
A few years later, Shen Hengyu entered Beijing. She called Huo Yunzhu "sister-in-law" with a smile, her eyes were gentle, and she was polite at every step, but she was writing down old accounts in the dark. Rumors, powder, poisonous tea, palace banquet framed, every time Huo Yunzhu handed out a knife, Shen Hengyu gently caught it and sent it back.
Pei Yanci saw the poison hidden in her smile, but he only felt happy.
She is not a good person, and he is not a gentleman.
One of them is gentle and sinister, the other is cold and defensive, they set up a trap side by side in the storm of Beijing, favoring each other, and the old covenant that was eventually taken away turned into a beautiful woman with a bright matchmaker.
