Plot
There is a theory that there are innumerable parallel universes outside this universe."If I was acting like this at that time ..." "If the dream of those days came true ..."
There may be a universe in which such an IF is a reality.
"You" who got a job to support a hero by chance.
"You" helped live the battle, which is the source of power for the heroes.
We will "observe" the infinite possibilities that people have.
