The rape was kind of random, it's like why...would anyone just want to do that out of the blue? Does the seme find it interesting to abuse someone who is already disadvantaged? It just seems like the author is trying to bend the story so it fits her own fetish. I like the art though and I like the characters, I only hope that the transitions and emotional developments make more sense in the coming chapters.
