What it says on the tin! It always struck me as odd that our goody-goody two shoes kings can be so rude to NCL lionesses (or in the case of our super nasty kings, not be rude enough!) when rejecting them.

In line with all the karma-specific text, maybe have alternate flavour texts depending on the Kings karma?
i.e Neutral is the exact text we have now.
Good is something polite and nice like 'You gently let her down and tell her she'll be someone's perfect Queen one day, she just needs to keep positive! You charmer!'
Evil is something even meaner like 'You laugh in her face at the idea that this shabby lioness is fit for your pride. What a joke! She walks away heartbroken.'

Obviously the text would be much better than this, but would provide a little more immersion.
Note I have no idea how hard it would be to code something like this, but it would literally just be changing the text on the refusal page depending on your Kings karma.
