Honestly i have a problem with the love/slut route for me at least if makes more sense if love rout would be locked under condition that Josepf and Adrian leave the house and its just Anna and PC in the house cuz the sharing scenes on both routs are preety much the same with minor differences or 1 or 2 scenes only in chosen route.
Making them more impactfull would be exclusive content like prostitution witch many people have mentioned could be locked to slut route as a means to make money and it would be just fitting to Anna being a slut.
Love route could have dates with Anna on weekdays PC moving his room to master bedroom and sleeping in one bed with Anna with her weaking him up with more exclusive scenes as well as going to sleep.
Also money is just to easy to come by there is a huge snowball effect no idea if that intentional but after few weeks and u can buy everything would be nice if the money was hard to get until the "late game" giving more puprose to pimping annd out. At some poing working at the cafe becomes irrelevent after we get all the scenes with the barista so there would be an insentive to work there also the cafe content could be expanded a lot more thenks to it maybe Anna promoting it on Starmaker and lewd clients could molest the barista or Anna could work there an a waitress for one day and she would be the one molested or flirted with clients resiving tips.
