Secret Royal Inspector & Joy

Kim Jo-yi states her case in front of the district magistrate to end a terrible marriage. Meanwhile, a new secret royal inspector is appointed.

When another body is found, Ra Yi-eon starts a murder investigation in secret. While gathering her friend's things, Jo-yi makes an unexpected discovery.

Yi-eon learns of the secret ingredient that may have killed the crown prince. Jo-yi leaves her home in search of a new life as a free woman.

Jo-yi and Yi-eon go undercover to save children from an abusive master. Their plan goes according to plan, until Park Tae-seo shows up.

Due to a lack of evidence, Yi-eon sends Tae-seo and Cha Mal-jong to be tried at a higher court. The prisoners get moving, but a surprise awaits.

Jo-yi and Yi-eon assume another disguise to enter Tae-seo's hideout. Park Do-su heads off to find his brother and the source of his wealth.

Do-su finds himself a guide who can lead him directly to Tae-seo. Jo-yi follows a figure in the night and comes across a startling scene.

While flipping through Tae-seo's trade records, Jo-yi spots a familiar symbol. Yi-eon looks for an official who cannot be bribed.

Jo-yi asks a tradeswoman to help locate her mother, unaware of the trap she's willingly walked into — and the shocking truths that await.

The king orders a crackdown on Park Seung and his allies. Jo-yi has a rough time adjusting to life in the city, until an old friend comes to her aid.
