If the mc is this much uninterested to have sex with all those beautiful/sexy/wanting women
(who have an actual reason (to have sex/make babies) to survive and maintain their culture/village),
then yeah might as well end this farce.
Tbh this kind of a guy in a setting like this is such a joke.
This manga's like some type of an intellectual/self-ironic statement,
about how retarded every japanese male protagonist is when he's surrounded by his harem,
and that he's just unable/uninterested to have any romantic development with any of the girls,
no matter how much they are trying to show their interest towards him..
(Though seriously, this is just bad writing with vanilla-trope protagonist, who prob doesn't even have a penis.
I guess he's actually an eunuch, or his balls still haven't descended from puberty)
Gotta admit it though that the art style is really great. (shame writing isn't of same quality)
The women's physique looks especially good and pleasing for the eyes. 👍🏻
