Once an Angel

This story is about someone's origin--a story about why it has existed.

Many people believed that this mythological creature was harmless and only had the responsibility of guiding dead people's souls to the other world.

However, what if there was a sole reason why it existed? What if there is something more than just a "responsibility"? What if this being is not completing a task but rather fulfilling a promise?

This tale tells the untold secret of the Grim Reaper, who was once a human who learned how to love.
