Comments of chapter undefined of The Conquerors Path

maybe it'll take 100 more chapters for mc to at least openly date both his sister and mother with them accepting each other , I can that happening in the future but I can't see them accepting any other girls outside of the family , maybe mira and Eleanor could join as well , but other than them ...not possible , it'll lead to a war , I wonder how the author plays it out at the end , but I hope it's not some simple stupid reason for them to accept the harem
