All I can say is, imagine the frigging self-discipline required to pull off this kind of ending. Most authors would not—could not—believably write this over seven books. And I don't mean in terms spice. That's easy. I mean in terms of payoff and character progression.
Part of what made Male Malfoy easier to write is that he remained a sniveling little shit until book 6. His female counterpart, as has been demonstrated, would be infinitely more likeable from the get-go. Maintaining that tension with the core trio while also going through most of the same story beats as the original Malfoy, would be an impressive exercise in self-control.
I don't think I've seen such a long-form transition from villain to hero without the author rushing it, or the audience wondering, "Wait, why are they enemies again after that big moment in the previous book?"
Except Vegeta. He is the quintessential tsundere.
I know the Internet’s going to Internet and all, but I do think some artists deciding to go the lewd route with this new character are completely missing the point.
People are hungry for traditional, genuine and romantic stories. Men especially, in my opinion. Malfoid’s existence allows the hero to save and get the girl and live happily ever after. Every guy dreams about having that at least once in his life, I’m convinced of it.
Maidens in distress are a literary trope as old as literature itself for a reason because of how deeply it touches us as people. It inspires the imagination. In contrast, all tradpub wants to push out is subversions, reskins and monster porn. A honest-to-goodness tale of redeeming and saving a fallen princess is downright subversive all on its own. We’ve come full circle right back to where we started: the dude saves the world and gets his girl. The world was allowed to change. The End.
So, let the R34 artists do what they want, I guess. Personally, I think they’re missing—or ignoring—the entire point.
But I’m just some dude who writes stories, don’t mind me.
