They aren't even going to turn into old hags regretting the moment they refused to marry earlier - they will simply not going to consider marrying at all.
And just look at how the Japanese sheeple think that they don't care about love and intimacy. What a crock full of nonesense. If that was the case the animal pets, host-clubs, escorts, visual novels, anime etc will go out of business.
It wasn't because they were workaholics etther - because even the NEETs exhibit the same behavior too
The real problem here is that the Japanese were raised to be afraid of real-life interactions.. Once again, reflecting back to my observation way back when that gal presented such an anti-social vibe to the people around her. Her insecurity and fear projecting itself from within....
