After the handshake ceremony, they parted hands and Diamond said to Essy, "I hope that you don't mind but I am in the middle of broadcasting LIVE right now," not wanting to hide that matter from Essy lest she had complaints.
When Essy heard that, honestly, she was shocked at first before calming down as a wave of excitement washed over her.
As a JEWEL, she knew about Diamond's antics. When she is broadcasting, those who didn't know her, wouldn't even know. Her drones were top-notch, and knew how to be invisible. She didn't think that the other would be broadcasting, but even if that was the case, she was still happy.
Not only did she meet with her idol, but she also managed to gain popularity. The fans liked things. Whatever Diamond liked, they tend to go and take a look. She had an inkling that her followers by the end of the day would see a sharp increase. And surely, she was right.
