——Bang!
When Bi Yanling left the office, the sound of the door closing was particularly loud.
Bai Qinghua completely disregarded it. Perhaps because he'd spent too much time in the gaming room, he didn't return immediately but paced back and forth inside the office, stretching his body, while gazing out the window into the distance.
Who knows what he was thinking.
The students in the office cast admiring glances towards their mentor.
The freshmen were fine, but the older students knew that for university teachers, maintaining colleague relationships is more important than teacher-student ones.
If it were someone else facing Bi Yanling's request, their batch of students might have had to organize an after-nine lab schedule.
Bai Qinghua basked in these admiring looks, hence continued pacing around the office.
"Teacher." Shi Qianqian filled Bai Qinghua's kettle, respectfully handing it to him.
