Right. While it's easy to say that it's just fiction, it's also necessary to understand that fiction can still have a hand in shaping a person's mentality. It's similar to the issue with young girls being obsessed about their physical appearance due to seeing so many photoshopped models.
As of late, I've had an extremely hard time finding novels that don't fall into this trope. It makes me think whether this kind of treatment is really starting to get normalized or if it's just being excused because the ML is good looking enough. I once complained about it and had someone get angry at me saying that love isn't all rainbows and butterflies. Although that statement may be true, I'm at a loss of what to think if blatant abuse is being treated to be on the same level as a simple argument. It's worse since most of these novels are targeting teens who will be easily influenced by it. Since, yeah, I get that are going to be adults who might find amusement in it for the sake of the fictional thrill or something while knowing full well that that's only acceptable in the fictional realm. It isn't a good model to be portraying to teens who are still experimenting and learning what romance is.
