The reason for this jarring description, Wen Nan guessed, is that it actually doesn't discuss the feelings of Wu Qing, the substitute assistant, toward the students at all.
This section implies Wu Qing's identity as a queen.
What it describes is the queen's feelings towards her subjects—
Similar to how one would treat their children, it says the queen loves her people as if they were her own children, adhering to the principle of "students' grades are above all else," stating the queen's "people-first" policy.
If this point is confirmed, then looking at the teacher-student relationship will have another explanation—
Wu Qing is the queen, and Wang Yajun should be a servant with special skills.
Servants follow the queen's orders, and the queen loves her people, so the two can form a stable cooperative relationship.
The reason for giving Wang Yajun an identity concealment card is to hide his special skills.
