What I don't like in these types of manhwa is that rape is portrayed as sex with extra steps which of course is VERY problematic. Despite that I don't think that in this case violence doesn't have a purpose (it could be less graphic though), as we see ACTUAL dialog instead of the shallow "Oh no don't". Yea we've established that they hate each other but at this point I don't think it's only about revenge but also their own inner conflicts. Both hurt and assert their dominance (in different ways) to escape from themselves too. Otherwise I think the story would've already ended with both or one of them dead.
