The Fiery Priest

They both deal with an MC who was previously involved with the military and is now trying to live a normal life as they deal with a traumatizing death in their past. They are then dragged back into fighting through meeting new people. Both shows also have awesome fight scene. But The fiery priest does have more humor then k2. Both are good shows.

When a member of a clergy winds up dead, a temperamental priest and a detective team up to solve the case.

The collaboration between non-police and police. The police also didn't like the priest when he first join the case but they start have good character development to him. Have a lot of crime plot also and really funny drama. Overpowered MC

The main character's are similar; their experiences and the hidden identity. The neighborhood squads similar too, hilarious, smart.
