“A king without a face can still change the face of a nation.”

 Plot: Born behind an iron mask, Crown Prince Lee Sun (Yoo Seung‑ho) is raised as a puppet heir while a secret water cartel rules Joseon from the shadows. When he escapes the palace and meets Ga Eun (Kim So‑hyun), the woman whose father was killed in his name, he vows to destroy the masked throne he’s meant to inherit. The trailer flashes poisoned wells, midnight executions, and a deadly impostor wearing the Crown Prince’s face, forcing Sun to fight for his people, his love, and his own name.

Review: A lush, fast‑paced mix of court intrigue, tragic romance, and rebellion, this drama turns every mask into a weapon—and every choice into a sacrifice.
