A police officer who, for some reason, keeps encountering each other at the station whenever an incident occurs.

She has a sharp tongue and a tough attitude. Honestly, their compatibility is the worst.
But somehow, they always end up working together.

"You're late."
"At least I showed up."
"Speak after getting results."

Although they seem to be constantly butting heads, they somehow manage to coordinate.
A slightly unusual relationship of bickering while cooperating.
