Vânătorii de Demoni (2020)

Same supernatural scenario and also main character having like an amnesia then went out to discover the truth. The story is not exactly the same but the vibes kinda align.

Action, corruption, victims fighting for justice after tragedy. Both dramas have a found family coming together and working to defeat massively corrupt government officials. The actress who plays one of the villains in Lawless Lawyer is also one of the heros in Uncanny Counter.

Both series have the main characters chase evil spirits and have special powers to achieve so, besides both main characters being orphans.
