The atmosphere of the whole Ec1 Comprehensive Junior High has been tense. For various reasons(excluding the previous attack on the campus) there have been many activities going on. Especially so to each class' individual clustering.
It is a well-established fact that each class has a deep rooted culture of intense competition. Each batch that enrolls upon this prestigious school is bound to give birth to an unforgiving study environment. That only the strong survives on its walls.
Now is the examination period. The higher years—graduating year particularly has a very tense environment. All sorts of tricks are found during this period. Sudden disappearance of notes, sudden diarrhea, sudden injuries and all sorts of suddenness. All for the sake of having the best grade for their class or for their own individual reasons.
