Gems = getting the girl
This game really gets your doki doki blue balled everytime there is that choice you can’t afford without paying money for it. All I know so far it really doesn’t matter what choices you make at all even so you pick the boring/neglecting one. All three girls will fall for you everytime, so going to this game don’t worry about your “choices” and just expect a basic romance novel that goes bulldoze over the story no matter how you “effect it”.
