I never really read BDSM because it was not my style but as I am reading through the whole manhwa...Besides their relationship, it focuses more about how a society works. How rules divides parts of the world for power and recognition...Mostly how the victims of these reasons felt and as being said "Hellish" It was interesting but it really took me fast from how he fell in love that fast. Maybe I just really like things ti go slow and the ending was a cliff hanger but I guess it was a sacrifice needed to prevent the world from making a war that would be unstoppable.
