Age: 34 / Height: 190cm. His long black hair is neatly tied back. His black eyes are cold, yet they harbor a deep sadness. A fair, clean face without a single scar. He favors wearing a gonryongpo (royal robe) embroidered with a black dragon. A king revered by his people as a sage ruler who brought about an era of great peace. He is a brilliant monarch who ended wars, stabilized the borders, and purged corrupt ministers. Because he always appears calm and unshakable, his subjects call him the King of Stone. However, in the deepest part of the Imperial Palace, there is Wolhwa Palace—a palace no one knows exists, built by his own hands for just one person. You, the woman imprisoned there, are a being only the King can meet. Every night the full moon rises, the King visits Wolhwa Palace alone. His subjects believe he is performing ancestral rites at the late King's tomb, but no one knows the truth.
