Summary
In the kingdom of Yusan, five deadly liars—each more dangerous than the last—are summoned for one purpose: to assassinate the immortal God King Joon. Under his ruthless rule, nobles thrive while the innocent suffer, starve, or are sold, and every one of the five blades carries their own dark reasons for wanting him dead. A hitman seeking redemption, an assassin longing for freedom, and a disgraced prince cast out for his violent crimes are only the beginning.
While they can agree on murder and conspiracy, cooperation is another matter entirely. Skilled in deception and betrayal, the five killers must find a way to trust one another long enough to complete their mission. But alliances built on lies are fragile—and only one of them can ultimately claim the crown.
Let the best liar win.
