- Both set in high school
- there are bunch of bullying and school violence.
- both of them are damn dark
The only difference is that The King Of Pigs has the older self of the kids while here it's just the teens.

both are:
-zombie kdramas
-bloody, gory
-if you like horror go for it!

Kingdom is my favourite kdrama since i started to watch dramas and it's really underrated. As i heard many people have seen AOUAD, so i think you should give a try to Kingdom! Kingdom might be a little different because it's in the 1500-1600 years and AOUAD is in 2021/2020.
Let's hype up Kingdom too!
