Adult PC Game: Projekt: Passion S3 Ver.0.15 by Classy Lemon Win/Mac/Android Archive

Overview:
Earth has long since been abandoned, and what remains of humanity is now spread out across the galaxy. So what happened at Earth? That part of history has long since been lost to obscurity.
But what do you care? You have your own problems to deal with.
You've just survived an assassination attempt at the cost of your apartment. Sounds like any other day of the week, right? Right, only this time your partner has mysteriously vanished as well, and it's your duty to find out where she went! Word of warning: the answer may lead to... bigger adventures than you'd planned for. Better pack an extra lunch.
