So at this point it's all but stated that MC is Qetesh's son right. This would make our peasant a demi-god. Some people might argue he's too weak to be a demi-god but my counterpoint is that he's a demi-god of sex & fertility, so his skils are different. But let's look at how this could affect the game & girls around him.
The second many women & girls meet MC they seem to be drawn to him. As long as he does things that endear him to them, they find themselves infatuated with him. It's only when they are neglected, abused or betrayed the "charm" seems to break. At which point they they will deny sex & berate him, but very rarely do they outright cut MC out of there life. I believe deep down they are still drawn to him (Mia is the exception because her grandmother acts as the barrier if MC dosent take responsibility).
It would also seem that MC is only alluring to females who are single or dissatisfied with their relationship (Jenny, Luthien, Josephine, Hilde), & as such there may be a reason Greta & Makith aren't drawn to him in the same way, Greta may have truly loved her late husband & cannot fathom another man replacing him, Makith is old & believes herself past all the mating, she may not even consider MC anything more than her King, and Annabelle's mother was happy with her bullman. This also makes sense when u realise that Qetesh is a goddess of sexual pleasure, ecstacy, fertility, & most likely love, so satisfied/elderly women may not look at MC that way. Why would they?
This also explains MC's love of impregnating & fucking his pregnant LIs. As a demi-god of fertility it's literally his nature to spread his seed.
That's is all lol.
