- both shows tells story about prison life/survival and have their characters developing time by time
- the main role from both shows accused guilty of their (too much) self-defense act
- both main roles were initially athletes
- both shows have comedies despite the prison life hardships
- Shark has Ahn Hyun-min character and Prison Playbook has Beobja/Jailbird character which I think both have quite similar entertaining vibes
