Honestly, I like Banache's expression on page 7. And that she's still reasonably aggressive. She's not malicious as the ex-fiancé, and she was quite often dragged around by him, so I don't think there's too much to forgive, assuming that she's grown enough to learn from her mistakes. Besides, that's all up to our Miss Money Pincher here. And Banache's cuter in this commoner style than in her doll-like appearance from before.
This is also one of the better reasons for being oblivious to love. Partially because she loves money too much, and partially because she's deliberately trying to ignore it for the sake of the first part. Willfully ignorant is usually more believable or acceptable than just being too dense. With exceptions, like Bakarina.
