Content-wise, I think the stories only get more satisfying as it continues. Canno's is a good opener and introduces the change of eras along with the ongoing theme of gay women speaking with straight women. Nega's, while the art is a little hard to follow, has stronger yuri themes and, in my opinion, has a more sympathetic protagonist. Kawauchi's is the most satisfying with plenty of nostalgia and happy but bittersweet feelings throughout.
The best word to describe this anthology: hope.
