The Imperial Coroner (2021)

Both are detective cases and are focused around female centric themes in the crime solving business. Maiden Holmes seems be more broad in the sense that the female lead can somewhat fight, is a detective that can find clues, and can determine death info. In contrast, the Imperial Coroner mainly focuses own one expertise. The female lead is much more well versed in determining the causes of death and symptoms it shows through the corpse. Her explanation is much more explicit and scientifically explained in contrast to Maiden Holmes which only offer generalizations.

In the final years of the reign of Jiajing Emperor during the Ming Dynasty, Lu Yi of the Jin Yi Wei is commissioned to investigate the disappearance of funds that have been set aside for river repairs in Yangzhou. He is assisted by Yuan Jin Xia of the Liushanmen. The two accidentally become involved in a conspiracy.
The talented female constable Yuan Jin Xia gets into a disagreement with the hot-tempered Jin Yi Wei Lu Yi over a case that they are both involved in. Jin Xia thought that she'd never encounter Lu Yi again in this lifetime, yet fate has its way of bringing two people back together. Government funds have been stolen and Jin Xia receives orders to assist Lu Yi in his investigation.

The Imperial Coroner is quite a bit lighter, lower budget, less political and more comedic but i couldn't help but think of it while watching Secret of Three Kingdoms.

The Imperial Coroner is another ancient investigative team. It is more of an ensemble cast but the way the cases are solved are procedurals, which is similar to League of Nobleman.

Pledge of Allegiance is similar to Imperial Coroner because they both have the same themes: wuxia, historical, suspense, with hints of romance

Both dramas are about ancient detectives, mysteries, deaths, crimes, investigation, forensic. Smart and quirky main leads. Fast pace stories.

They are obviously different, but the main actor is the same and with a similar vibe of an unsociable brainiac. Personally, I like his acting style.
