You mean no negative impact in the means of game mechanics?
I realized that Jun isn't just a robodoll for pleasure, but rather a person. It is implied that for some reason she may be more sophisticated than a sexbot should be. So in my perspective using her in a sex business is the same as pimping. Maybe worse than that given her being vulnerable, unaware of a whole story.
So I'd like to choose whether I want to do this to her, and to see how my decisions have a huge impact on dialogs. I am a grown man and have no sentiments toward fictional girls, but she is a purest thing, more potent than anyone in that dystopian society, so she deserves a good treatment at least.
