I think it should have more rape. Its kinda annoy me when a MC don't rape that bitch, Its kinda annoy me when the MC go all the way to the end of the novel without touching a woman, but still do all other mortal things.
It is not a 'china thing', rape is all over the world, but we (East) are a lot more sensive about it than the West. IM NOT SAYING THAT THEY DON'T CARE, im saying that they know that it happaned all over their history and they keep it in mind so it don't happens again, different from us who embellish our deeds the most and hide all the evil things we have done (and still do, look at the Middle East, all those soldiers raping women there, there even some humanitarian agent that trade food for sex).
About the girl falling in love, welp, you should have already heard that girls like the bad boys, right? So, it is this shit, but to another level.
Anyways, it is a fictional story, nothing to worry or go against if you can simple read another thing.
