I really can't blame the fmc for getting upset. "freedom to love" isn't something a nobles gets to have. Even if that weren't the case, she was ordered to get the prince and the other girl together, she can't just stop even if she wants to. Especially when she believes there is a risk of being...
Ya who would want to live in a world where your family and all modern convenience exist when you could live in a world where you spend your life in a tent and could be executed if someone doesn't like your food.
@Alterninjask given how her friends weren't even listening to her I doubt she's capable of being a major antagonist. She's more likely to be a running gag like the anime team rocket.
@Rozzak not really, he just wanted to use "helping" as an excuse to make her available. In this case it was totally for his own self interest. She is an adult in a relationship with a minor, reporting her would be the right thing to do. Not breaking them up to hide that she had done it.
