How Did She Know Your Surname?

"Which floor?" asked Xiangyi as they entered the hotel lobby.

Shi Nuannuan looked up at his handsome face. "Six!"

He smiled as he ignored the gazes of others and carried her to the elevator.

"Mr. Xiang."

A woman in uniform walked towards them. Shi Nuannuan looked at her. The woman looked like an employee of the hotel 

But why did she call Xiangyi 'Mr. Xiang'?

She was a little curious. After entering the elevator, she could not help but ask, "Did she just call you Mr. Xiang?"

He looked at her. "Yes, it's a polite form of address."

Well, that was true, and it was also how others would call her brother out of respect.

But what she was more curious about was that a hotel staff member suddenly called him 'Mr. Xiang' as if they already knew each other.

And she knew his surname was Xiang!

"How did she know your surname? Besides, she didn't need to look for you. She just greeted you out of the blue."
