Principal wasn't quite the evil jerk we thought he was after all! I guess there's always exceptions to rules and feelings.

NEET means Not in Education, Employment, or Training. Unemployment benefits expire within half a year so most NEETs are supported by family.

Principal only has two sons. The elder son is a successful CEO, a striking contrast to the younger son. Probably one of the two reasons Principal hates him. Can't blame him, I suppose.
