Does anyone have like a scene guide or a flowchart for this game?
Edit: to be clear I am not part of the pharmacy and I've helped anna. BOI seems to not be a thing
Nope, but would you maybe settle for a rough outline?
The PharmaFem route is the most developed and will allow you to reach most of the content. As you already discovered, BOI currently is a dead end, though no soft-lock, per se, as you can still date Kenya (maybe Scarlett, too), help the fugitive, and whatnot. Though you will be struggling for money which will make it much harder to go the feminisation route. The only soft-lokish route is the evil PharmaFem one, where you succed at the job interview but neglect to show up to work…
Going the PharmaFem route allows you to either play dominant, neutral(ish), or fast-track your feminisation (by wetting yourself on the inverview after having drunk your step-mom's breast milk – basically the submissive choices). Being dominant will allow you to be early and set up a date with Kenya, being submissive allows you to date Scarlett. It's possible to set up both dates at once, but Kenya will see you leave with Scarlett and later cancel, making them mutually exclusive. If you win their hearts, of at least their affection, you'll be introduced to a secondary character each and can further influence the relationship. In case of Kenya there's potential cuckolding on the menu, in case of Scarlett you can end up being a sub to her mom.
There's two other love interests I'm currently aware of, but seeing how I'm very much stricken with the fugitive and won't ever give her up, I can't speak for any police content, so… *shrug* Anyhow, one of these is the fugitive. Taking good care of her will allow you to see her naked, have her sleep over in your bed, and being shown her eye. The other one is Mathilde, the yoga instructor. Be a star pupil and she'll reward you with cock and love. So much
cocklove.
Hope this somewhat helps!
