The Good Virgin Route feels so... Plain and disappointing.
Try again, but boost the girls lewdness to C, and make sure to finish all the side events.
The virgin ending being unsatisfying likely because it's the general normal ending if none of the requires for the other ending are met, specifically the true love ending requirements.
For the past 5 games, save for Witch of Eclipse, OneOne1's reward for keeping the girls virgin or very close to it, through the whole a playthrough has been the true romance ending. It was that way for Samurai, Ideology, Oni & Blade, The Heiress, and Marauder of Dystopia. This game and to an extent Samurai shows OneOne1 breaking from that old trend. Which kind of makes sense as the girls' being virgin or not has no actual impact on the plot of their story
