Well the main part of this is smut. The author must be trying to make a different version of their own smut novel. Based on what I just read. The female lead suffered a tragic childhood. And that's how she's mentally traumatized and act on defense towards herself. As for the male lead he just play the part of her life a companion that will mark her as his beast mate. Since she seems to be an adult they made it this way so we could try and understand what kind of different story is this, with the weak minded female lead who only learned her whole live to fear being abandoned by her own family. Because the author is trying to make it completely different from other to avoid getting criticism from other who committed copy writing.
Your lacking on understanding about this kind of different version of story. This supposed to be a romance novel R19 version. This type of things was supposed to be "how would you feel if you were pampered by the male lead with innocent character but tragic childhood ?" As an innocent being just not to be vulgar who would jump on him once she saw him. I be honest I almost understand the whole meaning of this story even though I just dash on things to read smutლ(´ڡ`ლ) but I'm just here to learn more about human desires by just reading their life personal experience on this novel.
First, he’s grooming her. Second, it’s gross that she calls him master. Third, why does everything have to be so sexual like I get it’s smut and that’s okay but instead of comforting her to make her feel like she doesn’t have to lie or even just communicating like proper people he treats her like a sex doll who needs to be sexually punished. Like, full on FL is also extremely boring and complicit and has the personality and knowledge of a child so he is full on grooming her.
