A hot springs audio drama awaits you here, and while fanservice you cannot see, you can certainly hear.
Two short dramas plus a new song by N's on the first of Nogizaka Haruka no Himitsu's Drama CDs. There's going to be another one of these next month, so just because Haruka finished doesn't mean it's done yet. Of course, Haruka and company aren't the only ones this season singing about roses, but I shall get to that one when the time comes. For now, enjoy.
