The owl is an evil bird, born to eat its mother; the deer is an evil beast, born to eat its father.
The boy he rescued with his own hands turned out to be a monster. He killed his whole family, but left him alone to drink poison and hate.
His hands, which should have been used to save the world, became a murderous weapon of revenge.
However, he will still feel satisfied...
Just let him wring the sad man's neck with his own hands!
