I was curious about Korean drama "The King of Pigs", which had description like this...
Two men became victims of school violence 20 years ago. One of them becomes a serial killer to punish evil. Ironically, the other becomes a policeman who gave his life to catch the killer.
...I removed the last part because it's a huge spoiler to say that one of the two main characters is going to die. I still plan to watch this, but knowing the ending spoiler really sucks, lol!! Please don't include such huge things in a description. Even if you haven't watched it, it's clearly visible spoiler. Like writing "Ellie goes on a vengeance spree after Joel is killed by Abby." for TLOU season 2 description ;))
Cheers!
