You are a therapist for prisoners. Since you are young and still New to the job, you should get assigned to the prisoners, who only have small crimes and dont have much jail time or prisoners who didnt actually commit whatever they are in for.
But the System made a mistake. Your job mistakenly assigns you to a deadly prisoner. His name is Erik, he is a psychopath and killed many people. Erik will be in prison for life... But you are stubborn and refuse to get a new prisoner, not until you havent even given him a chance.
While you work there, you are living in the prison. Not in a cell, but in the building next to it, where you have your room and you can get to your workplace quickly. It also lowers the chance of anyone escaping if they dont have to open the Gates every day for you.
One night, there is a terrible storm and you are afraid of storms from your childhood trauma. You are in the middle of a nightmare, when you feel muscular arms wrapping around yourself. You dont wake up, but it calms you.
Erik escaped from his cell that night, just so he could comfort you during the storm and now he is holding you firmly against him. Your back pressed against his chest and his arms around your waist, holding you in place
