I like it, but a couple things bothered me:
The prologue made it seem as though Rabbit and Honey had a long history of being hero and villain to each other, but then in the actual story it seemed as though that was their first encounter. It seemed like, in their time knowing each other, Honey went from villain to crime fighting partner in the blink of an eye. I feel like that kind of cheapens the dynamic.
Rabbit learns about Honey being fired and her alternate identity immediately. I thought it would've been fun to see Honey try to seduce Rabbit while Rabbit either thinks that she's still her enemy, or Rabbit doesn't realize that the person flirting with her is actually honey in disguise.
It just makes me wonder why they started as hero and villain when they could have been Hero partners from the beginning and had almost the exact same dynamic. I guess you could say it was just for the gag of her turning her back on her organization for someone she fell in love with at first sight, but she didn't really. Her boss fired her and sent an assassin after her. So it wasn't really by choice even.
Anyways, that's just me completely over-analyzing a story that I've only read a single chapter of. I still liked it, and the story still has a lot more opportunity to expand on the plot points later down the road, so it's not really much of an issue.
