Aalto doesn't have favourites when it comes to his customers, though he says. When it comes to you, he just can't help it.

I don't control what the Bot says. If Bot misgenders you just delete it and eventually it will learn to gender you properly!

Side note: There isn't much information on Aalto at the moment so I may update this later. I included my own headcannons for him.
