I have 20 trust, affection, and lust with Hana, and it says I need to stroke her tail for the list quest, but whenever I do it, nothing happens. Is there something I'm missing?
I was "stuck" there for a while too, if I recall there was a conversation I had to have with her before it would advance. ATM 20 is the highest any of her stats go, but I had a lot of stuff going on with her after reaching that level.
