Ann... Well, even though she is a princess, she comes off as a wild child in front of Duanmu Huai.
On the other hand, Audrey almost became a duchess. She's somewhat similar to Miss Mary in terms of her noble status, but for some reason, Duanmu Huai feels Audrey is not as well-mannered as Mary.
"Ah, yes. For instance, matters like door etiquette, dressing up when going out, and the behavior at social gatherings. There are very strict rules for these. I was brought up with similar education since childhood..."
"I never noticed."
"It's probably because you seldom attend banquets. Even if you do, people don't really care much about your manners..."
After all, with his strong abilities, no noble with a brain would care to criticize the etiquette of a dragon slayer who can single-handedly kill a giant dragon. Not to mention, Duanmu Huai doesn't come off as a patient man. If he gets upset and slaps you, you had it coming.
"Nobles sure are troublesome."
