I'm really curious about the Chinese, why every novel was like that

Every start novel is always one nightstand and the girl is always raped. Why do those authors/writers come up with the same idea? Is it Chinese culture? Or do they just copy each other stories? To be honest I’m sick of it. Why not try to write something new, like your unique work, your own colors, your hard work, not copycats? And as the writer/ author If you can’t even find your own and come up with your ideas for your novel then don’t write it.
