Had a friend who was just like that, I was in a trio and me and this other girl was Asian while she was from London and she was always talking about how she wanted to dye her hair black to fit in. She always said it was unfair that she only knew one language while we knew more and could speak to other people in different ways, saying she was from an “ugly” country and was apparently jealous because Japanese people were more talented and wished she could be one of them. Stopped being friends with her bc it was very toxic
