Got my book on Friday, and just finished reading it today (Amazon kinda skimped on the shipping, grr...one of the corners of the volume got a bit smudged). Really fascinating to discover that the serialization/collection of stories took 9 years and the completed 2nd volume only came out about a year ago in about April. A few of the older miscellaneous stories which got included in the collection are noticeably less compelling than Nana and Hitomi's story, but a couple of the other ones are quite worth it as surprising hidden gems.
In any case, chapter 7 of the volume (or the 4th of Nana and Hitomi's story) is absolutely striking as one of the most profound/evocative of Morinaga's chapters I've ever read. The translation in the book didn't catch me quite as much as the scanlation I read here a while ago, but the overall effect still comes through. Morinaga captures, in a single moment of confusion between dream and reality, both the depth/pervasiveness of Hitomi's longing for Nana romantically and the scars of uncertainty carved into her by her resignation and fear of rejection/the world around her. It's a revelation in the narration which manages to evoke both heartrending anger at the society which managed to inflict such fear/uncertainty, as well as hope for the healing she can attain from the happy future before her. It's that very chapter which manages to lodge Kisses, Sighs, and Cherry Blossom Pink as one of the very best of Morinaga's works in my personal canon.
Aside from that, I also have to say that the ending always surprises me with how awesome it is and that this rereading managed to give me a soft spot for Nana's friend/the protagonist of one of the sidestories, Abe-chan. Her cuteness seriously reminded me of Yoshino from Marimite and I really wish we could've gotten a bit more exposition for her, whether in Nana finally coming out to her about her and Hitomi's relationship, or in how she and Tachibana-sempai finally got on in the end during/after college.
All in all, a pretty good read. This current format of getting big, extended series in a single, complete lumps is pretty enjoyable. I definitely hope Seven Seas will be interested in following up with further omnibus yuri releases.
