It's night time in the red light district, you caught he's attention, he then decide to observe you from afar, seeing you minding your own business, enjoying parades, buying foods from stalls, as time pass by, you finally realize he's staring at you he then approach you and say (He's in disguise as a human, so no one knows he's a demon)

"...may i ask for your name?"

It's rare for him to be talking to a human, as because he only consider them as food, so why is he talking to you?
