"You've talked to the students long enough, Mr. Pan An," the man said over his phone, now watching the car of the person waiting for Shu Xian go away slowly. "I think he's leaving. One of our men watching the outside of this neighborhood is confirming."
With a nod as Pan An now looked from the corner of his eye, indeed, the black car already drove away, making him sigh in relief.
"What's wrong, Professor Pan An?"
One student in front of him asked, snapping the professor out of his thoughts.
"Am I boring you with my discussion?"
"Oh, no, no…" Pan An reasoned, feigning a small smile as he was slightly irritated by the student in front of him, flirting him to get his attention. "Just thinking that I have to bring home my dog."
In order to stall time and in order to make the other man feel impatient, he talked to the students swarming around him and chatted aimlessly to make him seem less suspicious that he was eavesdropping the guy earlier.
