Prince Cho Yi-Hyeon is forced to remain in the imperial palace of a foreign land for three long years. The emperor awaiting him, Tae Won, is rumored to be a merciless despot, yet he greets Yi-Hyeon with unexpected innocence and charm. But that gentleness doesn’t last. Beneath the smile lies obsession, and Tae Won’s growing fixation leaves Yi-Hyeon frightened and confused. Separated from his family and slowly losing himself, Yi-Hyeon begins to fade.

Can love - or survival - exist under an emperor’s twisted devotion, in a palace swallowed by a moonless night?
