In this chapter, we learn that the guy who tried to climb over the wall and push the girl over to the other side of the wall is the same guy who wants to duel with the other girls in the class. The teacher tells the guy to keep his mouth shut, but the guy says he's going to give the girl's admission letter back to her. He also tells the girl that he has a duel with her and that he'll beat her up and make her apologize to him.
