One person.
A purely linear life.
From birth to death, it is just a period of wavelength. After it passes, it has no meaning. Therefore, there will be no desire to be born as a human again.
Two people.
It's just one more individual of the same kind, but life will become completely different.
It's amazing. For this reason, even if I go through hardships and painful reincarnations, I still want to meet you again.
You are irreplaceable.
