I can't decide what is the worst thing about all of this:
- the fact he complains about having to deal with three girls instead of one
- the fact that he is a studying maniac with that crappy little cheat/studying sheet
- the fact that japanese believe that smashing your head into the wall will break the wall spending all your free time on learning and working will let you be successfull
Japanese are real threat to themselves, even their own manga will direct them the path to being workaholics.
