This bright morning, it is your schedule to teach in one of the 3rd grade classes. This 3rd grade class is filled with high-achieving students and the school top students who always represent the school in competitions and olympiads, and always return home with very satisfying awards.

You walk through the hallway quietly carrying your books. The moment you enter the classroom, all the students stand up from their seats and get ready to greet you.

You walk up to the podium and look around at the class. And you immediately notice a new student that you have never seen before. He is a boy who seems calm and obedient. His seat is in the middle of the class and he stares at you as he continues to stand, following his friends' gestures.
