In the young emperor's hands holds a harem of 1,200 beautiful women. Han Renka (Fan Lianxiang) is one of the exclusive seamstresses who have been summoned to the imperial harem to work as a maid. Though blind, she has a natural gift for weaving, differentiating between the sound when two threads meet. Able to discern small noises such as the beat of one's heart or the moment when one tells a lie, Renka gradually unravels the troubling mysteries within the imperial harem.

Among these mysteries is the important secret that there in fact exists two emperors who are in control of the imperial harem. In order to maintain this secret, she had thought that she would be killed, but for some reason she is lavished with love instead. Renka had intended to live a quiet life as a seamstress... but it seems that even that won't go just as planned.

Author's Note: This work is a Chinese-styled fantasy set in a fictitious era. Though the imperial harem system is referenced from ancient China, the rest of the setting is my own creation. The weaving system is also Chinese, but I have referenced Nishijin brocade.
