Intro
Humans will all die someday.
I had never really thought deeply about such an obvious fact.
The spring of my second year in high school. I met a certain philosophy teacher.
Hokuto Matsumura. A teacher who was a bit cold, used difficult words, and was impossible to read.
But for some reason, I liked the philosophy room where he was.
When classes ended, I would head there for no reason at all.
"Sensei!"
"...You're here again?"
Those casual exchanges eventually became a precious time for me.
Sensei doesn't know.
That I am living while counting the time I have left.
And I didn't know yet, either.
That this encounter would greatly change both Sensei's loneliness and my life.
