This drama tells the tragic love story of King Jung Jong and Queen Dan Kyung, who was crowned and then deposed just a week later due to political power struggles. According to legend, after she was removed from the palace, the king would often walk to a royal pavilion and sigh as he looked toward the mountain where she had been sent. Moved by his longing, Queen Dan Kyung placed her favorite red skirt on a rock on the mountainside, letting him know she was safe—and that she still loved him.
