I wouldn't call it harem yet. MC more interested in their talents to build his Empire, rather than in their bodies. Question of marriage most likely will appear, it's medieval times, but if it does, I can't say for sure that it will be resolved through harem route.
For now it more focused on how modern knowledge can dominate medieval political landscape.
Promising but then i saw comments about harem so yeah thank for saving me from waste of time
