Inspirational version:
Life gives us a huge and infinitely noble gift, which is youth:
Full of strength; full of expectations and aspirations; full of aspirations for knowledge and struggle; full of hope, confidence and youth.
——Ostrovsky
Literary version:
All time is wasted
All time is wasted
What was lost, what was gained
There will never be an answer to something like this
I just occasionally pull out a certain paragraph from my memory
Pat the dust accumulated on it
Found out it turned out to be such a good time
protect them
Don't lose it
The above two versions can basically be ignored. The plot version:
A generation ago, a professor fell in love with a girl.
