O Novo Inspetor Secreto Da Realeza (2020)

Set toward the end of the Joseon era, Sung Yi Gyum places first in the state examination, landing him a position at Hongmungwan in the Administration and Research Department. Despite his recent success, he has no life goals, nor the ambition to realize them, if he did!

When caught gambling, Sung Yi Gyum, is punished and assigned to work as a Secret Royal Inspector. He is tasked with uncovering illegal acts and rooting out corruption within the ranks of public officers. He solves cases with the help of fellow inspector Hong Da In, a female colleague and his servant Park Chun Sam, who is talkative, affectionate, and often teary-eyed.

Sung Yi Gyum’s family consists of a nobleman father, his stepmother, a slave, and a younger step-brother, Sung Yi Bum. His father won’t accept Yi Bum as his legitimate son due to his mother’s low social status. As a result, Yi Bum is barred from seizing certain opportunities, creating a world of resentment towards his older step-brother, Yi Gyum.

- Historical-mystery drama
- Brilliant FL that assists in investigations
- Love rival with first love

Lovers of the red sky is a decent drama till Now . Royal of the secret agent is a really good.it has good actors, storyline etc . Just try it out .TRUST ME U WONT REGRET IT

I feel like through both of these, they are both quite funny, and enjoyable together. But as they progress they show more. Hopefully you will enjoy it as much as I did, both right now are currently ongoing.

Historical/mystery dramas focusing on a trio of characters. Both MLs are intelligent, top of their class, and end up leaving the palace, traveling to rural town(s). The relationship between the ML and his servant is very similar (more close friendship than master and servant).

If u (by any chance )want to see it's Chinese version then "My Roommate Is a Detective" has the same plot. It's the exact copy of "Secret Royal Inspector".

Mystery/historical/romance genre with the main couple working on investigations together.
....................................

.....................................................................

Both are dramas focusing on a couple investigating cases together, with a mostly light tone and a slow burn romance.

Both couples work together to investigate cases. Both dramas start out more heavily focused on the mystery genre, with a slow burn romance mostly toward the second half.

Both are mystery/investigation dramas in a historical setting with the couple solving cases together.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

They are similar from the friendship point of view ,,, Both dramas have good Bromance presence between the male leads and their good relation ship protecting each other may be one more than the other also Both has that Boss and subordinate relationship but they care about each other deeply

Ancient detective is a Chinese drama but it's too similar to this one ,, Both have cases in Historical time to investigate ,, Both have good Bromance between the intelligent royal or high class detective and his friend who is lesser than him ignorant and more of a subordinate to him
Both dramas have lots of comedic scenes and good laughs
Both dramas have slight Romantic stories not the main focus but the Brotherhood or the friendship is clearer in them both
