This is a good yuri manga. Being surprised at manga characters behaving like human beings paint a quite bad portrait of the media as a whole and yuri in particular. My gosh it is almost sad when what should be everyday is celebrated.
Just over and over, Akashi-sensei is too good to us. And you too, SAD! Sorry about your tumblr, hope you can get that sorted out nice and easily.
edit: Honestly? I'm kinda happy that there's only 3 chapters left. When you've consistently obliterated every obnoxious cliche trying to stop your story, it would be strange to suddenly slow things down for the sake of extending the chapter count. Besides, finishing it up means the author can dedicate their time to something new, and if that ends up being as satisfying as this has been then I'm very excited to go on that ride.
