Considering that main harem is just a small part of all the girls, that MC will bring to home-land + big help from angel/demon, I had a feeling that there were possible outcomes like:
1) forget about home, rule this land
1.1) forget about home, rule this land, your next generation will conquer your home. Yaaay.
2) comeback, overthrow king, give women to people, live with oyur harem
3) comeback, use help from a/d to lift curse
4) comeback, be a cuck and give ALL your women to people and get exiled again (cuck, remember??)
It just feels unreal, that MC (on a good path) will be able to gie up all the girls, that he collected and loved. MC also learns, that angel (light) and demon (darkness) used him in some sort of scheme and in later game catches one of them for interrogation.
Also from the very beginig it was clear, that MC wants to help people, but not goverment (that betrayed him and tryed to kill several times).
So yeah, I think in the end this game should have stayed true to it's name: "Harem".
