KotoHono! I really like these two, kind of an underrepresented µ's couple.
Though I like the cuteness here, I have to say the TL was kinda bad. Windyfall's quality is sometimes all over the place I feel like.
Not just typo like "I her her", but also things like:
Ah yes, it's my favorite µ's girl, Nnmi-chan! xD
Or "There'll be A-Rise's live being broadcasted tonight" - sounds really unnatural to me. Looks like a rushed release.
But anyway, at least we get to enjoy the second-years' cute shenanigans :P
