well that’s what natural in a series involing pheromones and rut/heat cycles and also they are shapshifter- animals and one of their needs is to produce offsprings too…also idk why you are asking about the heads up when it was always mentio here in the comments and mentioned in the novel premise too
First of all: I didn't read the novel.
And rut/heat and pheromones don't always mean that there is mpreg in the story. Many are just assuming. I need clear mentioning either in the story itself or the tags. Neither happened. It just appeared out of nowhere.
And shifters can be gay without having children.
And why should I read the comments for elements of the story that didn't appear in the manhwa? It should go without saying that the possibility of mpreg should've been clearly mentioned in the story.
I know many read the novel and are sharing their knowledge of it here in the comments and are comparing it to the manhwa. I'm just a little miffed that nothing of it was mentioned in the story itself. And if it was then in a roundabout way that leads to the territory of assuming. Kinda like a conspiracy theory.
This manhwa is on my list of my all time favorites. And so I want it to work out right. And the clear mention of mpreg and the theory behind how it works here is a huge part of it.
It don't like it when the manhwa don't mention things that are a no brainer in the novel.

Why is there suddenly talks about mpreg? This was never even slightly metioned in the story before. They only talked about pheromones and rut and so on, but not mpreg. A heads up would've been nice so it doesn't come out of nowhere.
