There's nothing I can do, Xue Song had a feeling this call would take a while, and he couldn't just leave the girl waiting in the cinema, right? You may not like it, but you have to be respectful.
...
Qiao Yu, who was having a great time on the forum, answered his phone immediately upon seeing the call.
As to how to make excuses, Qiao Yu had already drafted some ideas in his mind, after all, some things have to be faced sooner or later. Fortunately, this call wasn't about blaming him.
"Hello, Professor Xue, how are you?"
"Mm, Qiao Yu, that Yu Jianxiaoqian is really you, right?"
"Hehe..."
Qiao Yu laughed awkwardly twice, just about to start explaining, but the person on the other end directly asked, "Have you told anyone else about the equation's solution?"
"Uh, I only told Teacher Lan, but Teacher Lan said he didn't quite understand it." Qiao Yu said honestly.
