There are a freaking lot of cameos in this drama. And because of same writer between them Prison playbook cellmates cameo were the best.that last episode where looney shows up and they both were shocked to see each other hehe i knew it. He was with someone special (felt bad for lover he was so loyal)to live in Village was a kind of looney's happy ending version story.   Was crying for looney in prison playbook. Glad i watched this drama.
