It's interesting, in a way, even the 'good' ending feels somewhat bitter. Given the gender coding going on with predators and prey, it almost feels like a betrayal for Rain to take up the mantle of the breadwinner, the man of the house while the formerly strong bunny returns to her nature, as a peaceful docile creature.
I'm not sure if that dissonance is intentional or not.
Despite that, I really love the two main characters. Both of them are fascinatingly messed up in their own ways.
