-PROLOGUE-

Stay away from Danger Croxx. When his walking just at the halls, he has this aura saying 'Warning: I kill'.

But of course, when your Abstract Reasoning professor is as hot as him then why fail the subject?

And here comes Lucy Castellan, the math teacher who doesn't even know why abstract reasoning is a subject.

Lucy is that fierce non-smiling kind of teacher, but all her guy students came drooling after her.

At ang dalawang teacher na masungit, ay mag kro-kros ng landas sa 5 storey school sa loob ng... Janitor's closet.
