Difference of Lost Lives-III

In a blank, Hallow watched the way a human's life could go downhill. The boy's life was rough but he remain happy as he continues to think a positive life along with his sister who acted as his mental support.

Now, the girl, her sister had died and Hallow could see the despair on the boy's eyes. Watching this, Hallow remember again the true reason why he had been watching the boy's life. 

In the beginning, his purpose of coming was to pass to the abyss, finding a peace for his soul so he could retire from his position as the grim reaper. 

"Not wrong, that boy was you," came the voice from behind Hallow that shocked the little chick. 

Hallow had somewhat guessed it in his mind but can't help to be surprised from hearing this. He turned to see the person standing beside him was none other than the same creature who had guided him to the current room he was staying at.
