Finally got around to reading this - it's great!
I adore You-chan. She reminds me a lot of Hibike's Kumiko, in that neither are really your bog-standard 'good' protagonist. They're awkward and avoidant and stubborn and quick to justify things to themselves even when they know it's wrong. The difference here is that Hana is just about the opposite of Reina, and that will make You's arc, presumably, the opposite of Kumiko's (where Kumiko learned to be a 'bad' person/a villain for Reina's sake, and You is seemingly going to open up and be trusting/a 'good' person by being with Hana.
Or maybe I'm reading into things too much. You's introspection is nice, and I think the arcs so far, especially that with Kishi and Hime, while bittersweet, have been interesting and make me want to continue reading. You has already seemingly begun awakening to the beginnings of a crush on Hana, which is nice, and I think the fact that the author has already tackled - very explicitly - yuri love in the series means that they're likely not going to shy away (hopefully) when it finally comes to things between Hana and You.
I wish the chapters were a little longer, or didn't always end on such cliffhangers, but I definitely can't wait to read more.
