"I said, you're noisy. I don't know you, so why should I tell you my name?" Mu Xiaoxiao didn't like him very much, and thus wasn't very polite when speaking to him.
She thought about how this person had almost crashed into their car when they were going up the mountain and she just couldn't make herself like this person.
The rich boy thought that Feng Tianqi was going to get angry and was about to block him from Mu Xiaoxiao so that she wouldn't get hurt.
However, Feng Tianqi only laughed. "Are you not spouting nonsense? I want to know your name precisely because I don't know you. Or is it that… your name's so ugly sounding that you don't want to tell it to me?"
The last sentence seemed like he was trying to goad her into telling him her name.
Mu Xiaoxiao wasn't going to fall for his trick of course and she crossed her arms and looked at him.
