Together they escaped traps with the princess's wisdom
And they fell in love at first sight
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 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
