Born to a lowly palace maid, Prince Jin Yu-Su’s life is a split nightmare: a scholarly tutor by day, and the Emperor’s secret plaything by night. He endured the Emperor’s depravity, hoping for an end, only for the Emperor to die and his son to take the throne. But the young ruler looks at his uncle with the same predatory hunger his father once had. Commanded to become the new Emperor's concubine, Yu-Su surrenders to the cycle. If the son wishes to follow in his father’s footsteps, Yu-Su will make sure they both burn in the ashes of this obsession.(Source: Lezhin US)
