Is this a harem game? If so, will it be optional or mandatory to have a harem?
Its not harem type sure you bang everything that challenge you but you dont keep them.
I think that would be Up to the Character(You) to decide.
It does kinda hint at it VIA the Romance, like how some like Harems to show that their human is most palpable, and some don't as they find it unsettling.
