"Enter." Nan Zhubin called, looking over naturally.
Short flat hair, black-framed glasses, a faint unshaven beard, wearing a loose school uniform that completely obscures any body details.
A very standard image of a high school boy, and one who seems to perform well academically.
"Hello, teacher."
Upon seeing Nan Zhubin, the student immediately bowed, a 60-degree bow with his head down, and then stood somewhat awkwardly by the door.
"Hello, classmate, please sit down." Nan Zhubin quickly pointed to the seat opposite him.
Comparing to university students and adults in society, conducting experiments and psychological consultation with high school students is much more convenient.
——Because high school students exhibit an astonishingly high level of obedience when facing someone with the identity of a "teacher."
