Cokie Hua thought for a while and assumed that Stephen Yang was still on his leave so she planned to go to the top floor to take a look at everything and absorb some fullness as everything felt a little empty.
Cookie Hua always had permission to go to the top floor. Like a sloth, she moved to the elevator. It opened immediately and she got in pressing all the buttons which were there in the elevator.
It stopped from time to time and it felt really very annoying though. But Cookie Hua didn't really care about it because everything felt so empty in and out. Her eyes were randomly looking everywhere to spot something interesting but nothing really caught her eyes.
