Did I miss something? When did the prince start being nice to her

well she did grow up a lot since the story started haha jus the whole process wasn’t explicitly shown ig

well honestly aside from the arrow incident when they were younger he wasn’t really hostile toward her (for obvious reasons) and also he definitely gives off harmless himbo vibes, at least for now. like at the first party blondina went to, you could see that the princess was being far more hostile than the prince at that point. i don’t know if i’d call it nice, but they seem to be pretty chill with each other for now
