I've just replayed it after a few years and it's garbage. The amount of grind is retarded, the story is not about MC, but about some random bullshit side characters that no one gives a shit about (you might give a damn about 2-3 characters, not 50).
To unlock anal scenes you have to do 29 days of training, manually navigating through menus for every single one of them, doing camgirl streams requires a month of work renovating a studio for it, then all you can do is tease twice a week, it takes around 12 weeks to fully unlock all 6 or so scenes or 84 days. And don't even start me on the rehersals.
If you are not cheating all the way, every single day is cooking, working, taking care of MC basic needs, navigating between locations etc.
Making a song requires 10 inspirations you get in random locations, 10 times for 10 songs, then there are rehersals, trainings etc.
