A brave knight came to rescue her
One day, an evil wizard kidnapped the princess
Once upon a time, there lived a princess of the feline kingdom
And they fell in love at first sight
Together they escaped traps with the princess's wisdom
And the knight led the search of dangers
No obstacle could break the trust between the couple
It was difficult, but they had a hopeful dream down the road
And finally, they beat the evil wizard and escaped
And lived happily ever after
