I know Chiyo-chan is a type of cynisist and realistic type person, but imo, whether they will become rival at that entrance exam or not, the more important point is to help each other for that exam. isn't that the point of school? to study with other students, or more exactly, their friends (or in Marei's case, her lover

). added to on her own problem with the future careers, isn't it more efficient to study together then? instead of studying alone. more head is better in this case.....
