Lin Wan'er, a top student in the Department of Medicine, woke up and traveled through time to become the sick and frail daughter of the Shangshu Mansion. She was also given a marriage to General Zhenbei, who was rumored to be a murderer. On her wedding day, she gingerly lifted her hijab, only to be met with a familiar face—it was clearly Gu Beichen, the cold-blooded senior she had a crush on for four years in her previous life!
Facing her coveting concubine and her aunt who made things difficult for her, Lin Wan'er used modern medical skills to pretend to be a "fairy aunt" to accumulate connections while dealing with internal strife in the house. What made her heart beat faster was why the general husband, who was as cold as ice in front of outsiders, always failed in front of her? The cream cake that appeared inexplicably on the desk, the collection of love poems that quietly appeared on the pillow, and those "coincidences" that used the art of war to avenge her...
When war breaks out on the border and traitors in the DPRK and China stir up trouble, the lovers across time and space must work together to deal with it.

And as Gu Beichen's past life memories gradually awaken, a bigger secret emerges - their meeting may not be accidental...
