I'm reviewing this because the synopsis is sketchy and doesn't explain what the show is about. In short, it's about human sex trafficking set against the seedy drug underbelly. Ji Chang Wook fans will be disappointed because we hardly see him and I'd call him more of a supporting role here than the main lead. He's also very roughed up and not the pretty rom-com boy we're used to, so if that's your thing, look away now. He even looked better in Worst of Evil and that's a similar genre.

Overall, I find the show very messy, but maybe that's to reflect the messiness of life in this tier of society. I can't say it's my favourite genre either but I'd rate Worst of Evil much higher for more coherent editing and storyline. This one has too many time skips back and forth to explain things but the viewer has to go 'huh????' for a while first. And there were a lot of characters introduced in the first episode so it was hard to keep up.
