The note
Tang Enlai was the one that sent a mail to Glint, prompting Zhang Liling to issue a package to him.
And yes, Zhang Liling recognised as Zhang Xiaoling's husband, and that was the reason she was a little surprised with his mail and demand.
Tang Enlai had been annoyed with his mother's petty action to deal with his wife and having pity on her, he set out to do everything he could to get her an invite to the launch party.
He made calls to see if there was a way to get an invite, but none of them yielded fruit.
Left with no choice, he had to contact Glint through a mail to try his luck after taking a few hours to study the new brand.
After discovering that his mother was not bragging about how big Glint was going to be big, he decided that it was indeed worth the hype.
Although he had no reason to make Zhang Xiaoling happy after her treatment, he still set out to try to make her happy.
Contacting Glint and waiting for a response was by luck.
