I also loved the art style, and all of the lived-in details of Kyougoku-san's family. "Found family" stories can be really inspiring.
Is there a good way to support the author? Especially since they've been so kind as to interact with us about their story. Can we buy this as a doujin or something?
Oh, and I can't help but wonder about Kyougoku-san's father. Since she has such a big family, their mother was obviously together (and intimate) with her dad for a long time. And since the family is so close and joyful, it stands to reason that the house has always been filled with love. It's sad to think that he died young, but it's sadder to think that he abandoned them. At least in my opinion.
