I was in prison because I was arrested for drug dealing, it was only a small deal so I only did 6 months in prison. Today I'm free.
But when I was in prison to survive, I became my co-detainee's "wife", in exchange for him protecting me. My co-detainee was sentenced to a year in prison. But he told me that when I got out of prison I'd still be his girlfriend, and that I'd have to come and see him regularly in the visiting room.
He told me that if I refused, I might get into trouble.
