Zee interest in the twin
Mia had called ahead to make a reservation for them at the Scrumptious Restaurant while they were on their way there.
The Scrumptious Restaurant wasn't crowded as when it was first opened. There was no longer a long queue outside the restaurant as before.
The person working the front entrance recognised Mia from her previous visit. Thus, he immediately called for a server to assist Mia and the two men as they entered the establishment.
Mia had requested a private room in order to have more privacy. Mia usually sits in an area where she can people-watch, but because Zee and Ken had come with her, she wanted to make use of the chance to talk with Zee. She hoped to learn more about Ken from Zee as much as possible.
Zee had done a background check on Mia when she came to Infinity Gym for the first class with Ken. As a computer expert, Zee doesn't have trouble getting any information that he wants.
Thus, Zee knew about Mia's family background.
