Is there a way to decrease money grinding without cheating?
I've had a few promitions and yet I find myself grinding just for rent/debt and some Progression 3-4 days out of every week with the rest spent inceasing KP sloooowly by +1
Well, mostly of the time, you only could increase the girls' KP by 1 or 2 points, except in specific events.
For Bree, I increased her KP patting her head daily. Or, if you choose the 'video games' skill, each time you play with her, you will win, and gain +1 KP.
For Minami, talking about sex every day.
For Sasha, given her certainly answers in the early game. Also, you could choke her during the missionary sex scene and gain a good amount of KP.
For Shiori, I find that when she's asking Mike about some files that she can't find, you should tell her to 'ask Aletta'.
Speaking of kinky points, I can't find (well, I didn't try too much) how to increase them for Keilo, Anna, and Morgan (I think that the more feminine Morgan is, the more easily gains KPs).
