Oh-Kay ..... Sensei got fired for *cough-cough* "doing what should not be done" (especially on school property and during school hours), yet it seems that Shirosaki and Kunieda just might have fallen for him after he revealed his traumatic childhood, so that not only did he get a world-class deflowering/threesome combo, but they still came to *cough-cough, again* "visit", even though he's currently unemployed.
In The End, Was It Worth It? You Tell Us, Sensei ... You Tell Us.
