The tyrant King Hyeon, who indulged in male companionship, is known as the most cruel and debauched monarch of the Goryeo Dynasty. His reign was stained by the suffering of his people and the Emperor's perverse desires. To satisfy his sexual desires, King Hyeon forcibly dragged beautiful young men from across Goryeo into the palace, treating them merely as tools for temporary pleasure.

His cruelty extended beyond simple sexual debauchery and led to political tyranny. Without even glancing at the suffering of his people, he focused solely on his own pleasure and power. His palace was filled with endless feasts and debauchery, and the cries of the people did not even reach his ears.

The resentment of the people who commissioned you, an operative, for the assassination ran deep. King Hyeon's cruel rule had reached an unbearable point, and only his death was considered the sole path to save Goryeo. However, fate began to flow in an unexpected direction.
