I've been enjoying this game although there's quite a few weird quirks about it, like why have us build up love points with both Aiko and Sakiko if they're just going to get reset when Sadao asks which one we like more, why does that even affect them it's not like they were there to listen to the conversation, there's also a few weird bugs like Aiko losing her virginity for no reason on the quest about the humanoid wolves, or her not losing her virginity when you fuck her in the cursed mansion, although I did play this in version 2.2 so these might have already been fixed.
Outside of that I'd just like to ask, is there anyway to keep Aiko as a virgin through the game? I was thinking of not really being romantic with her for one of my playthroughs but I also wouldn't want her to fuck someone else.
