First-Person Deepening Techniques (Chapter 2.21)
Will you encourage Maya to rely on you? By helping you, she's already at risk, and the more attached to you she gets (and the more helpful), the more danger she puts herself in. The Boss will want revenge.
If we use enough Player toward NPC Chemistry Techniques, you'll want to look out for her. You'll need to defend her when the Boss, or one of his henchmen, comes gunning to get her.
Taking responsibility for another causes First-Person Character Deepening.
You'll need to decide how much you allow her to fall in love with you, once you learn you won't be able to take her back with you to your realm. We'd set it up in the game that there are small things you can do for her that make her more smitten by you but the more she's taken by you, the greater her heartbreak will be when you leave.
It might be nice to enjoy her affections, but will you be willing to increase her suffering later on? Wrestling with this decision is another First-Person Deepening experience.
