You know, I've been thinking. What if the reason that Shin's mom hates Hiromi's mom is actually that Shin's mom liked Hiromi's dad?
I.e., they were in the same situation as 'the kids' are now. Shin's mom = Hiromi, Hiromi's mom = Noe, Hiromi's dad = Shin'ichiro, Shin's dad = Miyokichi or some random fucker. Based on that Hiromi is now angry at Noe the same way as Shin's mom is angry at Hiromi. This would mean that their generation ended in a Noe-ending though.
Don't really have any new original art to post, posting shoop instead.
