That was really really good! And you know I was reminded of Kasimashi (it was my second yuri anime years ago, pretty good).
Truly the heart and mind of Kokoro can only be decyphered by Misaki xD but still, it's incredible that even in that ominous situation she found a way to see the world smiling even if she couldn't physically do it, she thinks that Misaki's words would be enough and that was my favorite part ...Because it sounds like a very Kokoro thing to do.
Thank you very much!! I feel like I might need to read it a couple of times more and maybe find different meanings to this story... It was a crazy doujin!!! I hope they get more...and an ova....and a movie
