It really doesn't require like a doctorate to understand the appeal of even the most filthy booktok fantasies. Idk why we're all pretending it's some kind of impenetrable enigma (this is sarcastic: I Know Why) that so many women wanna read about Men Who Are Dicks, Out Of Love
Like if you think about the experiences of heterosexual women for longer than like 20 seconds you can probably start to guess why "Oh he's a raging, violent douchebag, due to the singular passion he has for me" is such a common fantasy. This isn't rocket science
I'm not sure we need societal explanations for why Modern Romance Novels with Dark Edgy Love Interests are popular; there's a much simpler explaination of
1. Most everyone wants someone very interested in them and Hot. It's almost too common to state
2. Like explosions in movies or violent video games, some things are much more fun when the downside risk is null
3. Some people are subs
Some of it’s the fantasy of the person who does things to you without asking, but always does exactly what you want them to do, so you never have to communicate your desires.
... are people theorizing that men don't like Women Who are Dicks? Because I can tell you that this is absolutely not true, and if you have a gendered societal explanation, it seems like the existence of the opposite-gendered trope at least warrants a rethink of the forces at play.
Male romance fantasies absolutely include lots of the tsundere types, the stone cold bitch who melts with affection later on. This is an extremely common archetype. Tough exterior, hidden vulnerability? This is, if my understanding is correct, essentially what tsundere is, and this has a lot of appeal to men.
And the fantasy, if I can break my personal rule to not psychoanalyze tastes in media, is both one of overcoming a person's natural personality and issues (she loves me that much that her standoffish and bitchy persona melts away) and a fantasy of counter-signals to romantic attraction being false.
But I think this is just a general human thing, not something that we particularly need a gender studies debate to explain.
(I am willing to accept that women prefer this sort of dynamic more men, if someone has data to show that, but the data would have to be good data, and then we could start arguing gender role stuff after that. But I don't have the data handy, so must only make the point that this is both a male and female fantasy.)
