Hmm, I definitely want to see more.  It's a very cute relationship, and their development just doesn't feel finished at this point.  Also, Miu's attitude in general gave me very complicated feelings.  Morinaga's a real artist.  While the development towards a proper yuri relationship would from this point seem pretty straightforward, I am fascinated to see how she would actually handle it.
Thanks to Fly by Yuri for this great release!  It's a really engaging selection of stuff you've put out so far.
