Did Harmony just earlier and not sure at what point you tried to use Romance Novels but pretty much for me at least I couldn't give romance novels until I had done all the steps to get her down to 75 purity then you use 5 novels, they lower it by 1 point each, to 70 purity. Then you need to do the final picnic date to enable purity to be lowered to 50. Once you get her to 65 or lower purity and 25 LP you can date her. But you need purity to be 55 or lower to sex her.After some time without playing (since 20.1)I decided to try this game again starting a new game and I found this version a little buggy, like harmony do not reduce her purity is through "Romance Novels", or Sasha leaving the game even with collaring and 99 Kp (Bree in this case with 100 in LP/KP) Samantha try all time leave the game unless you go for patch B or C , Audrey disappear just moment my investigation start on the office and a couple event's who just no trigger even with required points and time with some character. I do not know if the Author start worried more about if players use cheat Menu or not and the things became little messy or decide the main character can't have "FUN " around anymore and became full of purity like harmony any way is wait a couple news updated to see and try again .
( if i kill some worlds or grammar please English is not my primary language. Sorry )
But yeah there seems to be quite a few buggy parts this time around when I finally decide to gather as many girls as possible in a single playthrough xD
