Okay so in the last episode, which is 19-20, we get to know the name of the corpse. When Dongbaeks mother abandoned her, she told her if anybody asks what her name is, she should just say its "Dongbaek". In the ending scene, the chief detective or whatever he's called he says, "Her real name was Choi Go-un", so could that be that it's actually Dongbaek who dies??? I really hope that my theory is wrongggggggg and not true;((((((((((
Honestly some of the best in Korea. I've never seen an actor/actress, convey a message in such a good way. It's so well portrayed, and you feel for them, almost like you are going through the exact same thing. it's absolutely mindblowing, seeing people being able to connect to each on such a high level, the chemistry is unreal. Such a beautiful tragic story, I'm honored I was able to watch it.
