Under the Skin

Kinda same genre.
Both starts with the death of someone very dear the one of the mc.
While under the skin has quite a no. Of different cases, if my memory is right law school doesn't have that much.
But either way both are very interesting.

In both shows the leads are socially awkward outcasts. They also idolize their popular love interest.

Under The Skin is also a cop show with a supernatural-esque vibe, and while there is no BL, the relationship between the ML's is really great.

Similarities:
- Jin Shi Jia is the main in both drama
- Genius ML
- Many murder cases to solve leading to the big underlying cases from the past
- Great investigation/detective drama + thrilling

If you like Under the Skin (season 1), you might like The Truth Within. Both feature leads who transfer departments and use advances in forensic technology to solve cases they have been personally haunted with. Mystery, crime investigation, detective police work, mental health, complex intricate cases.

- Both had interesting synergy between two male leads. Same enemies to bromance troupe.They first hated each other, but later on become close buddy.
- Both had same theme : Mystery,Crime,Investigation, Thriller

To be honest, I am not really sure why both dramas seem to give similar vibes. One deals with a genius artist joining the police (and has strong bromance), the other deals with someone who doesn't even like most of the police (and there definitely is no actual bromance). UtS spends a lot of time on separate cases, while TE seems to concentrate on a long-running over-arching plot.

And yet, there's just something really similar in the atmosphere they both project - like a dream state where things are what they seem to be but at the same time, very much different. If you've watched UtS (and watching TE), you might "get" what I mean.

Also, both have good soundtracks. At least that's an obvious common thing.

ETA Ah, there it is, the thing that made me feel there's a similarity (eventual reveal in ep 9). Both of these dramas aren't afraid to touch on VERY sensitive topics for mainland audiences. UtS did it more openly, but the police were capable there and no corruption in sight. TE decided to make it darker and not hide the rot under the pretty surface.

Under the skin is the first season.
Both of the drama has the same actors and actresses. Both main leads are present and the supporting cast is also present.

The two clash as Shen Yi uses unconventional methods to crack cases. As they work together, Du Cheng begins to see Shen Yi’s value, and together, they uncover the truth behind Lei Yi Fei's death, resolving their past conflicts and forming a strong partnership.

Under the Skin and Medical Examiner Dr. Qin are crime dramas with a ML who is a specialist in their field. The main characters of both share some nice bromance and friendship throughout their case solving.

Both dramas owe their existence to the works of Arthur Conan Doyle, although with Miss Sherlock it's more obvious.
Both feature an investigation pair with one partner being a genius and the other coming along for the ride to keep the genius safe and grounded.
Both dramas leave you with a craving for a second season.
