I understand what you mean. Take into account that Usanna's dynamics were very well thought out to be compatible with the protagonist's default personality (breeder trait).
I've added some dialog variations for Usanna, and you should see things clearer in case your protag is not a breeder. I'll touch on the love requirement too, in the next public release this should be implemented, I just ask for a little patience.
And thank you, I depend on my players' feedback to improve the game. I'm really sorry for the inconvenience, my friend. Hope the rest of the game is pleasing though.
