Beginner's tip
Thrillers love two timelines; if the colors turn warm and the phones get older, you're in a flashback. Episode counts vary more than in other genres — some seasons are as short as six episodes.
In Korean culture
Korean thrillers love mixing genres: a period drama with zombies, a crime story with a walkie-talkie that reaches the past. Some draw loosely on real unsolved cases, which is part of why they hit so hard with Korean audiences.
