Bai zixun didn't explain the reason, but teacher Zhao was surprised."Teacher Bai, this isn't like you. It's almost been a semester. As long as it's your class, you've never been delayed by anything. What's going on today? Did you encounter something?"
Bai zixun thought of Gu Yiyi and sighed in his heart. He said without any change in his expression,""Teacher Zhao, I really have something on today and can't make it. I'll have to trouble you for today. I'll substitute for you another day and treat you to a meal."
"Mr. Bai," laughed Mr. Zhao,"the other teachers would be so envious of me if I could get a meal from you. Don't tell me you don't know how to get a girlfriend?“
Bai zixun coughed and said indifferently,""Teacher Zhao!"
"Alright, alright, I was just joking. Alright, just leave the evening class to me."
"Many thanks!"
"You're welcome. If I have any academic questions in the future, I hope to ask you."
"Anytime."
"Alright!"
