Incest may be wrong but rather than looking at how wrong the topic is they should be looking at how well this is written and developed :D
i mean, the plot line is wonderfully written. I completely fell in love with the story.
it does happen in real life especially during anicient times. you know father - daugther are commonly i hear it in the news some times and siblings incest theres one case in germany but i don't know may be there are more lust is the root
