Hunters hunt deer.

Deer and lions in caves

A deer ran away from the hunter in desperation and ran to a hole where a lion lived. He was caught by the lion as soon as he entered the door. Before dying, the deer said, "I'm really unlucky." I escaped from the hunter and gave myself to the fiercest beast. "

The story is that some people fall into greater danger in order to avoid lesser danger.
