It would be interesting to know the kind of harem that
rojo123 intends to implement: if choosing one LI closes the others path, or if, on the contrary, you can choose for each LI individually.
In the second case, an election like the previous one would be frustrating for fans of the harem genre. In the first one, it would be understandable if both LIs are exclusive (that is, they cannot be part of the same harem). Personally I prefer option 2 (choose individually) to option 1 (choose one LI closes others)
In any case, right now I like all the LIs (I know 3: the girlfriend, the daughter and the daughter's friend), and I don't really see a reason for one to close the others path in a harem game.
Anyway, if there are several possible harems, I will always choose the one with the female MC (the daughter)
