Reverse the situation
The AI is in love with NPC and wants to interact with them on a more 'personal' level.
Now, it's the AI hiring the runners to get a body for it. (and paying for the runs with money it has stolen from corp bank accounts)
To smuggle the AI out from where it is.
To get it close to the NPC.
Now the questions become:
A) what does the corp do when it finds out capital is missing?
B) where do the runners get the 'body' for the AI? Is it a totally mechanical job? Or a heavily cybered meat puppet the AI wants to control?
C) what do the runners do when they find out who/what their employer is and what It plans to do?
D) How does the NPC react to the affections of the AI?? And how does that reaction affect the AI?
So many questions, plot turns, morality issues

If your creative you could spin an entire series of adventures around the concept (I know I did in my game:D )
