I'm very glad you had a look at the story despite your misgivings, and that you enjoyed it! :-) (I'd actually be interested in what you'd feared, too, if you want to go into that...)

I would have appreciated more on the Uchi front

That would have been a different story. :-) But it's great to hear that you liked where I went with it, anyway, even if you'd have liked to see more of Uchi! (Poor Uchi, this really isn't his story.)

I like how you write Junno, and I also liked your Ryo characterization (which, believe me, is saying a lot XD)

:-) Ryo can be abrasive, but in a way, that's part of his charm, because he's so much more than that - just like Junno is so much more than a silly grinning punster. Characterization is one of the most important things to me, so I'm very happy that it worked so well for you here!

Tsubasa's last name is Imai

Yikes! Thank you for catching that; I've changed it now.

Love the icon, btw. :-)
