Shu Xian didn't know why Pan An had called her out of the classroom. He made a reason that Wang Fang called for her but in reality, she knew that Wang Fang had a personal affair that she had to attend.
Why would he make a sudden alibi?
"What's wrong, Professor Pan An?" Shu Xian asked the moment they both went out of the classroom, Shu Xian acting like a student so no one would suspect them.

"P-Pan An?" Shu Xian now said his name, knowing that they're alone inside the classroom. "What are you doing?"
