I read in the comments "I also found it incestuous!?"
Incest is a blood relationship between parents, children and siblings (brother-sister) As well as close relatives - uncles-aunts and their children (1st generation) They should not create offspring because there is a high possibility of degeneration. Adopted siblings are exempt from incest because they simply do not share the same blood. That's all about incest from a medical point of view.
And the cultural thing is something else, for example for me as a woman from the West this series is very beautiful in all its dark reality where children are left to fend for themselves.
