He Is Psychometric (2019)

both dramas have a personage that have troubles to feel and express emotions. also they are about prosecutors, although in He is Psychometric this is not the main lead.

Both focus on crime solving using psychological methods. Plus, both has romance plots with yet with more focus on crime.

Male Lead similar ability. Which is the power of psychometry, the ability to read a person or an object's past through physical contact.

Castaway Diva and He is Psychometric though have different focuses are great stories. Lee Seung Joon plays the deadbeat father in both series that causes the family to run away and hide their identities. In both stories this father plays a crucial role in the development/thought process of the characters and pushed them to who they are portrayed in each show. If you liked one, I highly recommend watching the other. There is also the element of romance and reunion between the main characters.

Both are police dramas with a psychometrer ML .
Psychometrer Eiji is now old so it might be difficult to find the drama but I strongly recommand the manga.

The plots are not exactly alike, but the tones and the tragic type of stories were similar. The workplaces were also similar. The flashbacks the MMCs experienced were also similar.
