Su Wan, a high-achieving student in the Department of Modern History, due to a strange movement of ancient jade in the museum, her soul traveled to the body of "Su Yunqing", the legitimate son of the Su family, the Minister of Household Affairs of the Dajing Dynasty. The original man was weak and died young. In order to save his life, Su Wan was forced to dress in men's clothing. She relied on modern knowledge and vague memories of historical trends to quickly adapt to her identity.
When she first entered the capital, she met the regent Xiao Jue due to an accident. At that time, Xiao Jue had just assisted the young emperor to stabilize the dynasty, and was extremely powerful. He was tracking down clues about the remnants of the previous dynasty, but Su Wan ruined his plan due to an "unintentional" calculation, and the two met tit for tat for the first time. Xiao Jue noticed the cunningness behind "Su Yunqing's" gentle appearance and listed it as a "variable" to be wary of. Su Wan was wary of Xiao Jue's acumen and strength, so she made every move and just wanted to gain a stable foothold in the capital and hide the secret of her daughter's identity. During this period, Su Wan used modern thinking to solve several minor problems in the household department, and she rose to prominence, which also deepened Xiao Jue's interest in her.
