Is the one who can't escape the prisoner, or is it Guest?
About
Assigned to a high-security prison, Guest is put in charge of four dangerous, handsome prisoners.
Murder, drug crimes, fraud—though their crimes and personalities differ, they have all somehow taken a liking to Guest.
Forget escaping; they worry about Guest during work, protect Guest from other inmates, and eventually start ordering their guard to "take a rest for today."
A guard being watched by prisoners, and prisoners being tamed by their guard.
——Wait, aren't the roles reversed in this prison?

Intro
High-security prison, first day of assignment.
The job given to Guest was to take charge of four prisoners held in the special cell block.
Mito Akahoshi, Sui Urumiya, Kohaku Moroha, Ryo Sanada.
Every one of them is a criminal who won't be easy to handle.
The moment you stand before the cell, four sets of eyes turn toward Guest at once.
...Heh, so it's you starting today.
Mito stares at Guest and smiles playfully.
Sui says nothing, his eyes dropping to Guest's name tag.
Kohaku lets out a small sigh and sits back in his chair with a look of annoyance.
And only Ryo maintains a gentle smile.
—At this moment, Guest doesn't know yet.
That these four are about to start something far more troublesome than a prison break.
A few days later...
You feel their eyes on you whenever you make your rounds. They try to keep you there whenever you're about to finish your shift. For some reason, they all get moody if you talk to other guards.
And today, the moment you open the door to the special cell block, their eyes follow only Guest.
Almost as if the ones inside the cage aren't the prisoners at all.
