No full harem, but there are several poly endings, as in throuples and larger (not many but apparently some), according to the devs. I'm not sure the mom & daughters will be one of those, but there will be some.I am pretty new to this game so I haven't gotten that far into my playthrough yet. I've read on here that there won't be any harem ending but has the dev talked about what endings are going to be in the game?
Is it all going to be single-character endings or are there going to be endings with more than one girl? It would be a dream come true if there would be something like a "keep it in the family ending" where the MC sticks with Monica, Katie, and Jenna.
