I initially picked this up when I had only read about a dozen or so yuri stories. Even then I could tell it was a good story, but at that time I was still blessed with being able to read incredible manga one after another. When it seemed like every story was on the level of Bloom Into You, Kisses, Sighs & Cherry-Blossom Pink, or Bocchi Kaibutsu, it didn't occur to me that it was pretty special in its own right. I guess I was a pretty spoiled reader at that point time. I ended up putting it on hold, as it seemed to be straying further and further from Ayaka and Yurine with each chapter, and the change in perspectives was throwing me off. Anyway, I decided to pick it back up as I've had a lot of spare time and increasingly slim pickings for series to read, and I'm really, really glad I did.
I think one of the things that impresses me the most about this series is that each couple comes with their own distinct character dynamics and concise, well thought out storyline (perhaps with the single exception being Ayaka and Yurine, who instead have a comparatively slow, meandering storyline over the course of the series). I think Canno really shows off their creativity and talent for storytelling throughout the series, by depicting the many forms love can take and all the muddy emotions that can get mixed in with it. Not a single couple fell flat for me in this regard, surprisingly enough. Even the ones I was most hesitant on initially still managed to pull off their stories in a way that resonated with me. Another thing that really impresses me is the art, though I don't have much to say about that. It's gorgeous and wonderfully expressive. Canno nails the romantic scenes as well.
This series would've been 10/10 for me if it weren't for the final volume leaving a bit of a bad taste in my mouth. I think I'm probably oversensitive to it, but having couples suddenly define themselves as "intimate friends" is so absurd, especially since it doesn't fit at all with their relationship (looking at you, Mizuki, what are you thinking). The bigger issue, to me at least, was Ayaka's "I've never heard of love" esque journey. The entire situation made her (and some of the people she spoke with) seem uncharacteristically dense. On top of that, the whole thing felt a little cobbled together, since Canno was trying to fit in every couple as a final send-off. Of course, closing out a manga like this is nothing short of a herculean task, so I can hardly be upset about some of the goodbyes feeling awkwardly forced in.
All in all, it was a pretty incredible ride. The characterization was always fantastic - there's not a single character I disliked. My favourite characters are probably Moe, Yurine, Ayaka, Izumi, Amane, Haine... yeah I could probably just list the entire cast. Really incredibly impressive how well written the everyone was. The poly trio was lovely, Mizuki and Moe were excessively adorable, Asuka and Mikaze were touching and heartbreaking, Aika and Haine made me feel all warm and fuzzy (I'd like to think they're in love the same way the other couples are). Ayaka and Yurine remain my favourite. Honestly, there's a lot I'd like to say about all the couples, but if I did, this comment would be really, really long. Anyway, it's a 9/10 story for me.
