The love story between Shen Qingci and Gu Yunzhi.
Gu Yunzhi was a young and promising general. In order to ensure a stable future for Shen Qingci, he volunteered to go to the border. However, his whereabouts were unknown during a battle, and the imperial court named him Marquis of Zhenbei. As the unmarried "daughter-in-law", Shen Qingci supported part of the Gu family's affairs. After that, Xie Jingyuan, the new top scholar, appeared. His appearance was somewhat similar to Gu Yunzhi, and many details made Shen Qingci suspect that he was Gu Yunzhi, such as the way he held his pen, his understanding of the terrain in the North, his eating habits, etc. However, one of them was a civil servant and the other a military general, and they seemed to have many differences. In the midst of doubts and longing, Shen Qingci took care of Mrs. Gu while exploring the truth. The story slowly unfolded in the wind and snow of Chang'an.
