I just skip through everything, and this game really have potential with if it had an actual translation. You're forced to learn about all the girl with a quiz (that could easily be cheated) before getting into the main story. Then you have to guess who's actually cheating (?) with another quiz and route choice. If this VN ever get a manual translation, I will definitely play it properly.
Such a shame thought that the first girl had no sex scene. It's good for vanilla fan, but not in this NTR focused game. Even weirder that other girl get fleshed out NTR/corruption scene on their route, but we can't even see the first girl fully naked
