Imagine Japan competitiveness and dial it up to eleven.
It starts with kids, they have to be the best at school.
The thing is only 5% or 10% can be the best, the rest are failures.
Then comes work, the same people from school but older and bitter because they weren't in the 5%.
On top of that they have the K-pop idols, you can't be a fatso, you can't be an uggo,...
They have plastic surgery since early life because of that, imagine being a bug and hating it.
So all that combined turn most people into introverts, isolated and unhappy mofos.
That type of people don't interact with each others so sex don't happen.
