Shen Weilan, the daughter of the minister of Dali Temple, was forced to enter the palace and became the concubine of Emperor Jingyuan Xiao Che because her family was involved in the dispute over the heir apparent. On their wedding night, the emperor and his concubine made a "power plan", pretending to be a loving couple to stabilize the government, but in fact they were strangers to each other. In the harem, Concubine Hua has a distinguished family and is favored by the Sixth Palace. The virtuous concubine has hidden agendas. Concubine Rong has an old grudge with the Shen family and is surrounded by crises. Shen Weilan relied on the investigative skills and calm mind taught by her father to avoid danger many times, and gradually attracted Xiao Che's attention. When the clues of the family's injustice lead to high positions in the palace and involve the core of the struggle for imperial power, Shen Weilan is caught in a dilemma between maintaining the family's innocence and protecting Xiao Che. This "fake marriage" that began with a conspiracy has quietly given birth to feelings and is facing many tests.
