Ran Yu gritted her teeth, "She said they'll come over every night and teach me for a month."
"That's good."
Ran Yu was first taken aback and then abruptly looked up, "You think I'm not a lady of high society too, don't you?"

Ran Yu looked at him, just about to speak...
"Actually, when you're not talking, you do resemble a lady of high society quite a bit."
