Could anyone tell me who is who? I can't tell the 2 girls apart

One girl isn’t a noble but is wealthy and she usually wears fancier clothes and lives with her grandmother. The other stays with her uncles family. Don’t want to say to much in case it spoils anything. Anyways if your talking about their older selves then the one with straight hair is the one that lived with her grandmother. And the one still has curly hair.
