One day, a lion was taking a nap in the forest. Then, a small rat woke the lion up while playing on its tail. The angry lion grabbed the rat and roared.
"How dare you disturb me! I will eat you!"
The mouse begged in fear.
"Please save me, Lion! If you spare me, I will repay you someday."
The lion laughed at the mouse's words and said.
"A little guy like you helps me? Nonsense. But I'm not hungry today, so I'll spare you."
A few days later, the lion was trapped in a hunter's trap and became unable to move. The lion shouted for help, but no one came. Then a small rat appeared and ran to hear the lion's cry.
"Don't worry, Lion! Let me help you."
The mouse began to nibble at the trap's rope with its sharp teeth, and eventually released the lion. The lion looked at the mouse shamefully and said.
"I underestimated you. If it wasn't for you I would have died trapped. Thank you so much!"
