I've watched so many Hollywood TV shows and Korean Drama series. But Prison Playbook is something else. The main reason is all the casts were perfectly did a great job and the background score was so fantastic and emotional. I do appreciate the Director for a great screenplay, it was far better,unique and different from other K-Dramas. I'm a Bangladeshi?? I had no intention to watch this one but I finally did it. It's 2022 Now and I'm realising that I was too late to watch it! I became emotional and I was touched well whenever I listened those Background musics and songs. They were perfectly perfect. Enjoyed this Drama a lot. Thank you
