Su Run, a history student, woke up and dressed as a "fake eunuch" in the Dayan Palace. Because of her beautiful appearance, she was targeted by the new emperor. I thought it was inevitable to escape the "Longyang Disaster", but unexpectedly it was revealed that the emperor was actually a daughter! In order to consolidate the imperial power, the empress used coercion and inducement, and ordered Su Run to pretend to be herself and visit the concubines on her behalf. From the daughter of the chief minister to the daughter of a general, from a foreign princess to a beauty in the harem, Su Run was forced to deal with the warring girls and swallows to "solve problems" for the empress. On one side is Bu Bu's shocking crime of deceiving the emperor, and on the other side is the overwhelming catastrophe of love. Can Su Run break out of the siege amidst intrigue and beauty and take charge of the harem?
