I just noticed there is a lust stat opposite a love stat.... So I guess that is the corruption part of the story. If the Females have High Lust and low Love stats it affects the females. "shrug",
I remember having a few exchanges with Loys and Forefinger on Discord some time ago. If my memory serves me right, the original plan was to have differences in Love/Lust routes(as you can see in scenes early on), but due to update schedule(it was one update per month - one of the best schedules from any devs in here) stuff like this was gotten rid of.
At this point, it's a kinetic VN with cosmetic "Fuck/Don't Fuck" choices.
But if you ask me about some kind of canon and what fits characters the best - it's Julia love/Cassandra lust.
Also, why some games bring on new LI or postpone sex until the very end of the game?
Because if you don't have a story which can take your mind off NSFW narrative, then pre-sex updates are the ones where tension is the biggest - the expectations are at max and LI makes that final leap from "NO", "Maybe somewhere in the future, but still no" to "I wish I could say yes" and that final "YES".
The prime of this game was Cassandra falling for MC. The story was thrown out the window at that point, but there was chemistry. Now there's none of that, imo - story, despite their efforts to revive it, is irrelevant and scenes with LIs are just fucking for the sake of fucking. Oh, and threesomes.
