I am honestly quite confused about this game. I liked it when playing it, I played the Shota-Route and it was great. And afterwards I got a complete save and checked the Recollection.
But it does not really feel like a male protagonist game, it is more of a female protagonist corruption game. Because the male MC is just a bland person and the only real use for him is to see the H-Scenes.
And this gets even more extreme if you consider that this game is an NTR-festival. Because from what I have seen, if you do everything "right" and avoid Ryoka getting taken by anyone, you will get a good ending, but it is dialogue only. So there is not really any way to see any H-scenes if you want to get the good Ending (or at least not the good H-Scenes).
So, yeah... For me, it is more female protagonist than male protagonist, even if the male PoV makes the scenes hotter.
