Can someone explain to me how the subway minigame world and how to beat it to ger to work in time?
Depend of how you want to achieve that.
First, to be on time, you have to exit the subway when time left indicate + or - 0:20.
If you want to finish it quickly and don't want to get her molested :
Satisfaction will not interest you, but when the gauge is full the guy cum and leave you alone, when it's at this point you can exit the subway.
Will is how bold the guy will get, to make him leave quickly, you have to reduce this gauge to 0.
For that :
Hit the evaluate button, it will unlock the ability to see what verbal action have a huge impact on the will gauge.
As you can see below, the left capture is before you evaluate the molester and the right is after hitting the evaluate (3 time with the skill bought, don't know how much time without it)
Now, to make the gauge goes down, you have to hit the Green or Yellow buttons, Green has a huge impact on his will, yellow less impact, but they will still decrease the stat.
You can also use the physical action Push, he can dodge, but if you hit him, this will also reduce the gauge.
When the gauge is empty, the molester will leave you alone.
If you want to see her molested, it's the other way around.
Hit the Red and Orange buttons, don't push him, when he try to disrobe you, let him, so use verbal actions, and wait.
When he's satisfied, he'll cum and leave you alone, you can dress up and leave (often you will still be on time)
And there's a lot of animated variations of scenes here to see. And honestly, it's damn hot.
