More comfortable solitary confinement with kickbacks from inmates
By sending them to (therapeutic solitary rather than punitive solitary)
There was an incident where kickbacks were received.
The prison guard was later arrested
It was also revealed that the kids who gave the kickbacks were a Cambodian criminal group.

It was also revealed that although he was a prison guard, he lived as an errand boy like a member of a criminal organization.
What I got for doing this
70 million won for 8 months
It was a significant amount of cash, services, and products.
Because the money given by the Cambodian criminal organization is actually the money for domestic voice phishing damages.
I just took a bribe with the money from the crime.
