A resonant "Come in!" prompted An Ning, who was at the door, to enter without a second's delay. However, she left a small crack when she closed the door.
Inside the office, Sun Qian was perhaps too worked up to notice An Ning's subtle move.
After An Ning entered, Sun Qian was busy with some files, not even bothering to lift her head.

"Are you having trouble understanding the files, Professor? Or is there a difficult problem you need my help with?"
Sun Qian remained silent.
"Oh... I'll be on my way, then."
Just as An Ning turned to leave, Sun Qian slammed the folder in front of her shut.
"What kind of attitude is that? Is that how a student should act toward a teacher?"
An Ning, already at the door, half-turned, wearing that faint smile Sun Qian detested.
"I'm a student, which means I'm here to learn from my teacher. My attitude will simply mirror yours."
