A Médica legista Imperial (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.

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.
