Waaaaait! I had to stop working for a min to get this off my twisted chest. Sensei weighed his options and quit, once those two kids were hooked on him AND before the cat got out of the bag. He knew that it was just a matter of time before he got busted.
BUT
He also knew that there was a 50/50 chance with those 2, and that is why he went back to the school. When he said, I just want to see him from a distance & when he was talking to the little girl about who he loved, he was talking about both of them. His life must be every Pedo teachers' wet dream.
I love this kind of twisted :)
