Chapter 11 was not really focused on their age difference. The friend character jabbed at them because of it, and Wako poked back that she was old to be single, but that's kinda it.
The parents are so amazing, like, i mean, yeah i guess its kind of wishful thinking but this reminds you that even in a society so patriarchal like well, the japanese, there's people who love their kids just as they are. That made me shed a tear. Wonderful
So glad we're getting so much of this series. I can always use more "happy relationship" yuri, especially with adult characters. These two are just so adorable!
