Based on the tragic Joseon legend, this drama is about the love story between King Jung Jong and his Queen Dan Kyung, who was crowned and deposed within the span of a week due to rival political factions that controlled the king’s rule. According to historical legend, after the queen was dethroned and removed from the palace, the king would walk to the outside royal pavilion every day and sigh as he gazed at a mountain in her direction. After hearing this, she placed a red skirt, her favorite to wear in the palace, on a rock on the mountain face so he would know that she was well and that she still yearned for him.
