Since this thread showed back up and I've finished Hiver, I'm going to put out my wholehearted and earnest recommendation for Flowers once again. Especially now that you can go in to the whole series and experience all of the ups and downs without years of wait.
Of course, there are certain things I'm... Not necessarily unsatisfied with, but they leave an awkward feeling for me, namely... Yuzuriha and Nerine playing an antagonist role. It just seemed strange that they would come back following the events of Automne, and we're not really given much clarity on why. It's ultimately an unanswered question that I would dearly like to know the answer to.
But there is also some very positive stuff, like when Yuzuriha is grilling Erika regarding her crush on Suoh. It's cute to know that before Chidori entered her life, Erika had one-sided feelings for her bookworm buddy. It makes me wonder what a route centered on those feelings would've been like. And yet, it's also endearing to see how her feelings for Chidori have helped her move past that crush. The relief when Chidori came in during that scene was very cute.
Ultimately, 8.5 or 9/10, I hope one day Miki Sugina and Innocent Grey will hurt me once more with a wonderful yuri.
