The Uncanny Counter (2020)

Kinda remind the vibe same as Mystic Popup Bar since it's a supernatural genre for both. Some part in the mystic popup bar does fight the evil spirit too. Futhermore, they work in a team.

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.
