Imo the part where the dragon was basically a child (no education, no deep understanding of the world) and not grew up as in learn more over years, and had a father-son relationship with Taehyun (i forgot his name). Hyo-un made himself GROW body wise. One of the MANY reasons why children can't consent is because they don't understand the weight that comes with a relationship/sex, and Hyo-Un didn't know that at the time, even if he was an "adult" physically. Same goes for people with mental handicaps, they can be adults but sometimes they don't understand sexual relationships, therefore making it morally wrong to have a sexual relationship with that person.
In that case, wouldn't that be "beastiality?" Why have sexual relations with a species who is entirely different from yours considering human consent doesn't even exist in the animal world, so itd be considered rape. Not to mention, despite being older than Taehyuk, Hyo-un acted like a child and didn't know anything about the world, nor about humans themselves. You can't honestly tell me you looked at him emerging from the river and thought, "ah yes, that's a mature adult dragon, who can make decisions for himself?" This is not something you can argue without looking extremely questionable btw.
Yes, a dragon is technically a beast, it's based off of animals and has godlike powers. Doesn't make it human, nor does it have the same morals and worldviews of a human. And you're misinterpreting my intentions, which was to just agree that those chapters of the story made me uncomfortable, regardless of it's fiction or not. I wasn't seeking it, just using it to justify that discomfort.
I can't lie, there are some parts of this story that really make me cry, and there are some parts that are genuinely too weird for me to ignore but the porn is so good that I don't think I'll catch myself dropping this any time soon
