Ahhhhh, I finally watched the anime and caught up to the manga. Honestly Nakatani's way of presenting a story has to be the best thing I've ever read in yuri. There's always a level of ambiguity to it that leads the reader to a conclusion instead of outright stating it. It's what makes her characters feel so real. The understated way she draws them and how she chooses to have them express themselves is also realistic. I can really see these characters being real people.
Also the entire drama between Touko, Yuu, and Sayaka is something that's actually done really well. I suppose it's a love triangle but the way it's done actually does them justice. I think one of the reasons I like it so much is because none of them are the antagonist. Everyone has a story and their own reasons for doing things. This extends to the rest of the cast too. Each person has their own thing and they feel like real people. It makes me like everyone instead of just liking the leads.
Also another thing, I didn't think I could relate so hard to Yuu, but she really feels like she's asexual. It's nice to have someone I can relate to, but my favorite character ended up being Sayaka. I feel like she's what I've wanted to see a lesbian character portrayed as, and her struggle to accept herself is also something I can relate too. I just relate to them so much, and it's nice because I don't tend to feel like that for other yuri manga. This has gotten kinda rambly, but I just really love this manga. It just feels so....well written and real.
