She once said that human beings are fragile. To us, they are like mayflies that live and die quickly, but they are extremely warm.
He replied: People are human after all. Is it worth it to be extremely greedy and jealous?
She was silent for a long time, it was worth it
. . . . . .
He came to their burial place and stood there for a long time
Until he saw the child and the monster accompanying him, the human being was warm after all, although he resented but longed for it.
So he stood silently in the dark, observing (watching) them and watching them go through many things.
Man, time is too short after all. There is only this life, but it is an existence that cannot be erased from my memory.
Brief version
This is a silent (black-bellied) monster watching (participating in) the story of a human being and a monster.
