Synopsis:
On the 7th of his life expectancy, the god who gave happiness at the end was "Reaper."
"You will die seven days later." It was the Reaper that appeared in front of the girl with an intractable disease.
As usual, to the Reaper who hoped to be crying and begging for life-
"Did you come to teach? It's kind."
The girl just smiles.
(Is there a guy laughing to me as a Reaper ...?)
This is the story of the first age of the Reaper, who was first affirmed, and the girl who did not affirm the existence-"love" that would not leave even if he died.
