He doesn't want to attract attention.
"Alright then." Xu Xingguang tells Fang Jinsu, "We'll have dinner at Mr. Fang's house tonight."
Fang Jinsu smiles sincerely, "You're all welcome to come over."
He wants to have a good relationship with Xu Xingguang, eager for her to visit his home.
"Director Zhen, my A Zui is quite interested in photography, so today let him sit behind the monitor with you and learn a thing or two. Meanwhile, you can use this chance to assess his skills."
"Who knows, maybe he'll perform well and you two will end up as master and apprentice?"
Xu Xingguang's words are so charming that Zhen Wang can't find a reason to refuse.
When it comes to work, Zhen Wang becomes very serious. He tells Huo Wen'an, "Learning beside me is fine, but don't disturb me." He especially hates it when people mumble around him while he's working; it's very annoying.
"Alright, then I'll trouble you."
