^ You hack her PC during late night with the password from her diary when the game tells you to, then go sleep, then MC should wonder if she made some pron movies, go to your PC, click the "linked" icon, go to her camslut app, click it, then videos on top, check what she's made. Route should continue from there. You might also need to either catch her dildo'ing herself for the cammers and/or buy her new toys (if the game tells you to, if you go too fast, you'll lock yourself)
Phone hints for her route are pretty straightforward and tell you exactly what to do/buy and where to go/at what time
