i think theres the argument that it showed how humans view/treat androids and the ranking they have in society. and the actual rape was not shown but implied, which is more tasteful than a lot of other manhwa.
tbh i feel like we shouldn't be completely against the representation of that stuff in media? like it should be talked about. jumping on something immediately for just suggesting that shit like that happens in the world isnt rlly helpful imo. a content warning for it would have been good tho
