It's all set in this one neighborhood that's mysterious and dangerous. There's almost always a crowd, but the people are grayed out and fade into the background.
Interesting people stand out and they're all "main" characters in their own way with complex back stories. Sometimes they're doing something interesting and the story follows them, but other times they're in the background of someone else's story, just working or living.
When characters interact, it's almost random or coincidental. They form unlikely friendships. Some characters even only know each other through chats!
There are also the occasional novelty characters that are only around an episode or two that feel a bit like failed immy experiments, while others characters get strong enough to become urban legends that are whispered about to newcomers.
It's all a lot like how I view the fictional relationships of the characters in Sindome.
Anyway, I just wanted to share that random thought with the community. It's on Netflix in the US if you haven't seen it before.
