It's a bug which will be fixed in 0.19.4
Bug Fix:
1b. Buy a new house - The information screen incorrectly displays "Waiting for Naomi story to advance" when Naomi and Moko are not present. This issue only affects the message display and does not impact the game's core logic. - Fixed.
Great game with great detail, I love the expressions, excellent sound, it would be good to focus on BDSM and its girls because Lydia is alone, the others are better, for example Desire, a good model, and Julia's, that should be changed and the rooms should be enlarged, they are details that the player sees, but you are the number one developer.
