/**
In a peaceful pond, Fred and Freda, two ordinary frogs,
fell in love. Fred's charming croak caught Freda's attention.
They shared laughter, dreams, and even faced a rival frog.
Fred's daring leap won Freda's heart under the starry sky.
Their love story became legendary in the pond, and they lived happily together,
a testament to love's power.
