Our comments: As always, it's a great honor to be working on another Hibike! Euphonium doujin! The Minami Jr. Girls make for wonderful couples and I'm glad there are works dedicated to them.

Update: Sorry for the mistake, Pg.22 had the P.S. missing from the afterword. That has now been fixed.

Update #2: DL added in. Sorry for the wait!

It's funny how there's almost no pure yuri doujins for Euphonium. It seems popular and it was pretty yuritastic. Thank you for doing this one Gungnir.
