My interpretation of Neige is that he has 100% pure intentions, but was taught bad things by his parents. He was adopted for his beauty and turned into a child star, and his parents made sure he knew how to succeed. He would advise people to do harmful diets or suedo-science detoxes completely believing that theyre nothing but helpful. His mindset is a grindset but he can't even realise his own burnout because he was told that this is good, this is how you succeed which should be the only goal. He's sweet, so kind, but he puts no heart into anything he does because he's not doing it for himself. He's like a machine. That's why Vil hates him so much, because Vil can tell that his heart is not in what he creates, and yet he gets so much more love than Vil, someone who puts all of himself into everything he does. I adore the idea of Vil HATING Neige and Neige just thinking theyre friends! He doesnt see Vil's passive agressiveness as bitchy because he doesnt even know what that word means.
In general my idea of RSA is that they're the same as NRC, but show it in different ways. If NRC are misguided and hurt people who naturally do bad things as a product of their environments, then maybe RSA are blinded by their comfy upbringings and toxicly positive world views. I think RSA would be kind of about putting on a face and caring about how youre percieved. I really hope RSA isnt just "these are the perfect good guys," because that would make NRC feel dislikeable by comparison. If NRC arent truly evil, then RSA arent truly good either.
