I think it's it because they're close to that childhood friends, they're kinda thought that Akane will ended up with him.
Especially when they haven't net Yamada yet, so they didn't know what kind of men Akane is dating.
It's normal to be worry. I mean, Akane's mom even heard that Akane spend the night at Yamada's house.
