Well this seems interesting, though difficult to tell what direction it will head to.
Renako's issues with groups and whatnot are certainly pretty relatable at least.
Both Mom and Shima have great reactions, now we need to see if Mai has inherited the same reactions from their mother like Shima has but I can't see her getting in a situation where she'd react like that.
Good to see that the second chapter keeps continuing with the yuri the same way the first one did.
And thanks for the translation and the notes, was really nice and informative.
