Why Dong Zhenzhen would be here, actually isn't hard to imagine...
The course arrangements of the school are public and transparent. Even if departments are different, for Dong Zhenzhen, a teacher, to check the schedule, wouldn't that be a piece of cake? Once Gu Changsheng's class time was confirmed, and Mr. Gu is not a resident teacher, she could just wait at the door for him.
It's just that no one knows...
How long she had waited!
Sigh.
What a hassle.
Gu Changsheng was very clear about all this. Still, he pretended to be oblivious. What could he do? You can't fault a person trying so hard, right? A woman shamelessly pushing forward, it just doesn't seem proper to speak too harshly to her, so he just said, "Mr. Dong, don't you live in the teachers' dormitory? Why are you off-campus so early in the morning?"
Dong Zhenzhen wasn't flustered at all.
