>>108361869I'm going to spoon-feed it to you because you caught me at a good mood, anon.
Ao lives with her parents, so “meeting them” is a given. Here are several clips where Marine mentions meeting Ao's mother, mainly. Not to mention that Marine literally stayed overnight at her house and they did a stream (where Ao's mother appears multiple times).
Also, the fact that Marine took Ao to meet her family was because Ao introduced her to hers first.
She has interacted with both of them multiple times.
