Quote: “A mask hides a face; a crown hides a war.”

 Synopsis: Joseon reels under drought as a reborn Pyeonsoo Guild privatizes rivers behind silk screens . The masked sovereign (Yoo Seung-ho) hunts a missing edict naming the traitor, while rumors paint him a puppet . Ga‑eun (Kim So-hyun) returns as a reformist teacher decoding water‑tax ledgers , and a palace inspector in disguise (Jin Ki-joo) walks the razor between duty and betrayal . Trailer flashes moonlit hanok roof chases , ink‑poisoned tea, a bamboo‑grove duel , and a tribunal where the mask finally cracks. To save his people, he must reveal the face the nation needs—or drown with the crown.

 Rating: 4/5 — Lush sageuk intrigue with aching romance and sharp stakes.
