Looking for the best dramas within these genres!

I've already watched:

Signal

Cruel City

Bad Guys

Triangle

Missing Noir M

I Remember You

Love Me if You Dare

Healer

I Hear You Voice

Liar Game

You're All Surrounded

White Christmas

Can't remember more right now.

These have been my favourites within the genre, so I'd like to watch similar dramas. It's cool if it has romance, but I'm focusing on the other genres. Psychopaths are a bonus! Thank you!

P.S.: I had to drop City Hunter because it just had so many clichés /: I'm indecisive on giving it a second try.

City hunter is good drama
Remember-War of the son (this has a really good psychopath as the main villain)
Two Weeks (A bond of father-daughter, a real drama)
if you dont mind japanese these are so good action-suspense I highly reccomend
Bloody Monday
Kurosagi
Kazoku Game
Ouroboros
Orthros no Inu
Zeni Geba
Maou
Gap Dong
Mysterious Summer
I'm Home

All of these are great thriller dramas with a bit of psychological twist. Hope you'll enjoy them!
The Devil is amazing. You might also check out Pied Piper, Resurrection, and Time Between Dog and Wolf. If you're looking for psychopaths, H.I.T. with Go Hyun Jung and Ha Jung Woo or A Man's Story (by the same screenwriter as Healer) are good options.
