Although this drama may have been inaccurate from the historical descriptions that depicts, Lady Jang Hui Bin as a wicked concubine during those years, but it was also good that this drama was made and describe the other face of the history, as we know that during their era, it was the northern faction who rule the court and lady Hui Bin was one of their enemies at that time, actually there are some issues that lady hui bin became a political victim because lady hui bin is from the southern faction during their times, thats why it is good that they made this drama so that we will not learn or understand her story in a one sided way.
I just love all the aspects of this drama, the music was great, it was dragging and the actors portrayed their roles in the drama, we might say that king sukjong has a younger aura than lady Hui bin, maybe because lady Hui bin is actually older than the king himself..
