Yes. It is a moving, well-acted Korean historical drama for viewers who like intimate stories set against palace politics; expect sentiment as well as intrigue.

In Joseon-era Korea, a royal warden tasked with guarding a deposed king discovers that loyalty to the crown and loyalty to conscience may be incompatible.
