"Mm-hmm." After hearing Director Xue's words, Gu Yu actually nodded in agreement.
"You...!!" Director Xue felt like he was about to be infuriated to death by Gu Yu; he pounded on his desk forcefully and roared at Gu Yu, "Call your father over here!! I want to talk to him personally about this matter!!"
"Okay." Gu Yu nodded, then reached into his backpack to get his phone, and in front of Director Xue, dialed his father's number.
The office of academic affairs suddenly became eerily quiet, so quiet that the dial tone from Gu Yu's phone could be heard.
"Hello?" After a few rings, the call was answered, "Xiaoyu."
"Dad." Gu Yu looked up at the academic director in front of him and then calmly said to his father, "Do you have time to come to the office of academic affairs at our school?"
"Now??" Gu Yu's father was startled, then hesitated, "I can't right now, Dad is working on a report that the leader wants to see by seven o'clock."
