The game will end with the epilogue. Doing the daughters romance would pose a lot of problems for me:
* I would have to explain all the girls' growth in one game. Since he is not the typical VN absentee father, that affection has developed over years and is already there by the time she turns 18. Developing that relationship before they turn 18 would violate F95zone's Rule 7.
* For players who play without the incest patch, it would be a game that would not be connected to My Dorm, as they don't want to see incest and would never have a relationship with the MC's daughters.
* It would not be publishable on Patreon as it contains incest that could not be hidden.
* It would be a huge game. Too many daughters of varying ages. Plus the mothers of those daughters would still be around. The screen time for each of the daughters (and mothers) would be ridiculously small.
The epilogue would contain some nods to the relationship the MC is going to have with his daughters, both in the patched and unpatched versions.
And even if no one cares, it will also show his relationship with his sons.
