Actually, there is a scientist explanation :

The pheromone are issued by all the animals, they have an important role in the sexual behavior of animal while it tend to be minimal for the human, but they still have an effect.

Among human, we can smell pheromone of other wich is propagated most commonly throught sweat, it actually help us to have an unconscious first opinion of other persons, and it unconsciously influence our partner choice, certain people will be attracted by certain people via pheromone.

Of course this attraction didn't depend of the personnality of the person, so it didn't attract you to your soulmate.

But now what's about monster?

Monster can feel these pheromone even if there not the same species, they are potential partner, and by adding some magic in the process of evolution, it's safe to assume monster have an improved "pheromone detector" who allow them to analyse a man pheromone precisely, to the point they can know if a man is "compatible" with them.

Of course, scientifically talking, this last part doesn't make sense, but like I said, add a bit of magic is not too much since it's a fantasy setting.

Also this is totally the kind of change who would be develop by mamono since they need to find a reliable husband for survive/ensure there sustainability.

Of course it's just my perosnnal theory, you can just say "shut up,it's magic", but I find it better to link it to the pheromone since it make some sense.
