This is the compilation volume 2 of the "Himitsu no Recipe" series that used to be serialized in Tsubomi (yuri compilation). I say, "used to" because, well, this is the last volume, and also because Tsubomi compilation itself ended publication even before this series completed.
And it shows, because it ends abruptly. It's a happy ending, but it feels so forced to end that way, probably because the series needed to be closed out. Too bad, because I really like Morinaga-sensei's yuri manga. Still, Wakatsuki's daydream scene where she rips open a (beep) package is epic! What the heck was she going to do with it!?
The last chapter is an additional unrelated short story, and I like it a lot.
I'm listing this under Tsubomi series to keep things consistent.
