Set in a future just-unified Korea with human-like robots. Slow going, for me; it feels like it might be translated into English (awkward word/ phrase choices, doesn‘t quite flow) but I can‘t find evidence for or against. The blurb does give away a twist which isn‘t revealed until part 2 (ch 9 of 51). The narrative (3rd person, past tense) jumps between 3 people but I‘m finding it difficult to get into their heads.
