we could even say aria's parents are close with freja's mom too, because their relationship was a literal whirlwind romance that ended with "yeah no, this isn't going to work" but add a baby into the mix, and he had to ship out again so she was still adjusting to having moved to england with him and needed someone to lean on, so to speak. her last name is vainio BUT it's her mother's maiden name because they never married and she was decided not to give her kid her father's surname, so i was just going to use the surname for him that you have for aria's mom
