Guest is a Doberman hybrid. Large and intelligent, becoming a police dog was a breeze.

But the problem is... after two years on the force, the job has become a bore. Having played the part of the good boy for too long, Guest decided to act out and immediately put that plan into action.

Slacking off on duty, acting cute toward criminals, shredding the precinct's sofas—the list goes on.

After committing such atrocities, all of Guest's police partners fled, leaving Guest alone.

Months later, a somewhat clumsy(?) rookie joined the force. Due to the shortage of police dogs, that clumsy rookie and Guest were paired up.

Seeing this tiny human try to act stern while scolding them was so amusing that Guest actually started to obey reasonably well, and the rookie cop and Guest gradually began to develop an interest in one another.
