Kdramas covering crime & revenge

Hi guys!

Looking for ‘uncomfortable Kdramas’ - as in something that covers uncomfortable topics and crime like murder and other stuff in a realistic matter ( as in the main character isn’t absurdly strong or has super powers ). I’ve currently been watching A Killers Paradox and I really love how it covers such important and more darker aspects of humanity and how well written it is. I also love how it covers numerous stories, rather than just solely focusing on the main characters revenge like other kdramas.

Shows alike to my description above, that I have seen: Taxi Driver A Killers Paradox Girl from nowhere ( Thai, but follows the same premise ) The glory ( however, this is more so her taking her own revenge ) Extracurricular ( Did not enjoy because of FL ) Mask girl ( Uncomfortable, but again her own revenge more so )

All kdramas I have watched ( Exc. the ones I have not finished): True beauty Business Proposal Crash landing on you Mr Queen Moving Strong girl bongsoon Strong girl namsoon Vincenzo The glory My name Taxi driver Happiness
