Kill My Sins

- Grey, atypical MCs
- Both MCs are common people (doctor and magistrate in KMSins, bailif and judge in RT)
- Cold case investigation related to an arson case
- Tight and thorough plot with interesting twists
- Intimate and heartfelt storytelling
- Great acting and team dynamics
- Both are dark and gritty and deal with heavy themes

Both has:
- cunning FL and ML
- ML might want to kill FL at one point in the beginning of the story
- FL is no damsel in distress who need a prince
- amazing friendships and relationship dynamics
- revenge driven plot and characters
- poverty is a strong theme
- amazing actors

Difference:
- SoPG has romance, KMS has strong friendships and companionship between ML and FL
- KMS has heavier topics, SoPG is more business orientated
- more intrigues, corruption and scheming in KMS, but SoPG also has some of that, it's just not the main focus, like in KMS

The characters are not black or white but grey. Everyone is clever, not only the leads but also the villains. Twists and turns, but no real romance.

Similar feelings.
This has the vibe, smart lead. No romance, just like chess. Can't miss a sec. The characters are interesting. Here we go thru death trap together.
