Duty after School: Part 1 (2023)

Similarities:
- similar thrill and suspense
- good vs evil subplot
Differences in Kingdom:
- low on humor
- zombies
- period-based
Pros of Kingdom:
- more episodes
- satiates your hunger for apocalypse shows after DAS, trust me

Someone recommended Kingdom and season 2 is must watch too. Both series are about people fighting to survive in the world full of creatures that want to kill them.

part 2 of train to busan. similar thrill w zombies being the difference. survival and escape is the motive

Both dramas gave apocalyptic vibe however in Dark Hole there are zombies/monsters that attack people who have to fight to survive.
