There Is a Planet in My Brain

I'm just complaining, no malice, just a normal comment. The protagonist's geography teacher is really strict. When the protagonist is distracted in class, he uses the three major attacks on poor students: "throw chalk, yell ferociously, and go to the punishment station." I thought the protagonist is a poor student who often offends the teacher, but some of the protagonists later help the teacher buy a globe. This is really inexplicable. Anyway, my teachers in all subjects will not use special tactics on the confused students. They are all normal attacks to remind the students to ask questions by name. 🤫
