Thanks for the explanation!
With that in mind, have you considered an optional harem route? Something difficult to unlock, where the player can be with several girls, but with the possibility that they find out and there are consequences, such as jealousy or conflict. This would add more depth to the game, as players would have to make careful decisions to maintain relationships without breaking them.
I understand that this is not the main focus, but it could be an interesting extra route.
