I would absolutely love a proper vanilla doujin with the same competency in the writing department at romance as something like a big name mainstream romcom, that halfway through the story turns into a full blown hardcore netorare story.
It wouldn’t be a surprise or cheap plot device however, the bull would be introduced early in the story, acting like a proper supporting character, and there would be plenty of foreshadowed and hints at his true nature.
The cucking would also have a logical and reasonable place in the plot as well, where it would be kind of unexpected but not retardedly coming out of nowhere.
I’m thinking something like the classic trope where a misunderstanding happens and there is a false confession, and then the bull sees the perfect opportunity to shoot his shot at a very vulnerable target that he has been grooming throughout the story.
I guess he would have to be either a senpai or perhaps even the new young teacher.
Dream NTR story here, a long romcom manga where you get absolutely invested in the story and characters, and then turns into netorare in a realistic manner.
