Born as a concubine's child, Gwanghae was proclaimed as an heir to the throne. Gwanghae suffered from the threats of dethronement and assassination for 16 years because of his background.
This drama is the epic of Prince Gwanghae who used face-reading skills as his weapon to overcome his destiny and become the king.
And there is a woman, beloved by both Gwanghae and his father King Seonjo, who denied himself to qualify for the throne.
Because Prince Gwanghae was able to read others' faces, he succeeded to govern the Joseon Kingdom.
